We look at the division of 86012309 by 438 
We're looking to find how many times 438 goes into 86012309.

Let's proceed to step 1:
If we divide 8 by 438, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 438

Advancing to step 2:
438 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (0) from the dividend, add it to 86, then carry on: 860 / 438

On to step 3:
438 can be fit into 860 1 times, resulting in a remainder of 422.
The next digit of our result is 1. 
Result so far: 1.0
If we take 438 away from 860, we end up with 422.
Fetch the next digit (1) from the dividend, attach it to 422 and continue: 4221 / 438

Moving on to step 4:
When dividing 4221 by 438, we get 9 with a remainder of 279.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 3942 away from 4221, we end up with 279.
Grab the next digit (2) from the dividend, add it to 279, then carry on: 2792 / 438

On to step 5:
If we divide 2792 by 438, we get 6 and a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 196.0
Subtract 2628 from 2792 to get 164.
Grab the next digit (3) from the dividend, add it to 164, then carry on: 1643 / 438

Step 6:
The number 438 fits into 1643 3 times, leaving a remainder of 329.
The next digit of our result is 3. 
Result so far: 1963.0
The remainder is 329 after subtracting 1314 from 1643.
Bring next digit (0) of the dividend behind the 329 and repeat the process: 3290 / 438

Let's proceed to step 7:
If we divide 3290 by 438, we get 7 and a remainder of 224.
Record the quotient 7 as the next digit in the result. 
Result so far: 19637.0
If we take 3066 away from 3290, we end up with 224.
Append the next digit (9) from the dividend to 224 and continue with: 2249 / 438

Moving on to step 8:
When dividing 2249 by 438, we get 5 with a remainder of 59.
Record the quotient 5 as the next digit in the result. 
Result so far: 196375.0
If we take 2190 away from 2249, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
When dividing 590 by 438, we get 1 with a remainder of 152.
Write down 1 as next digit of the result. 
Result so far: 196375.1
The remainder is 152 after subtracting 438 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 10:
The number 438 fits into 1520 3 times, leaving a remainder of 206.
Record the quotient 3 as the next digit in the result. 
Result so far: 196375.13
The remainder is 206 after subtracting 1314 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 11:
The number 438 fits into 2060 4 times, leaving a remainder of 308.
Write down 4 as next digit of the result. 
Result so far: 196375.134
If we subtract 1752 from 2060, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 12:
438 can be fit into 3080 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 196375.1347
The remainder is 14 after subtracting 3066 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
438 can be fit into 140 0 times, resulting in a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 196375.1347
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 14:
1400 divided by 438 is 3 with a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 196375.134703
Deduct 1314 from 1400 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 15:
When dividing 860 by 438, we get 1 with a remainder of 422.
Use 1 as the next digit of our solution. 
Result so far: 196375.1347031
The remainder is 422 after subtracting 438 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Advancing to step 16:
The number 438 fits into 4220 9 times, leaving a remainder of 278.
Record the quotient 9 as the next digit in the result. 
Result so far: 196375.13470319
If we subtract 3942 from 4220, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

In conclusion, the division gives 196375.13470319 with a balance of 2.78e-07.
