86439562 divided by 230 
We're looking to find how many times 230 goes into 86439562.

On to step 1:
The number 230 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 230

On to step 2:
230 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 230

Advancing to step 3:
When dividing 864 by 230, we get 3 with a remainder of 174.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 690 from 864 and we're left with 174.
Include the next digit (3) from the dividend after 174, then repeat: 1743 / 230

Moving on to step 4:
230 goes into 1743 7 times with a remainder of 133.
Write down 7 as next digit of the result. 
Result so far: 37.0
Deduct 1610 from 1743 and we're left with 133.
Include the next digit (9) from the dividend after 133, then repeat: 1339 / 230

On to step 5:
230 can be fit into 1339 5 times, resulting in a remainder of 189.
Record the quotient 5 as the next digit in the result. 
Result so far: 375.0
If we take 1150 away from 1339, we end up with 189.
Bring next digit (5) of the dividend behind the 189 and repeat the process: 1895 / 230

Moving on to step 6:
230 can be fit into 1895 8 times, resulting in a remainder of 55.
Use 8 as the next digit of our solution. 
Result so far: 3758.0
Subtract 1840 from 1895 to get 55.
Grab the next digit (6) from the dividend, add it to 55, then carry on: 556 / 230

Advancing to step 7:
When dividing 556 by 230, we get 2 with a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 37582.0
Subtract 460 from 556 to get 96.
Take the next digit (2) from the dividend and append it to 96, then repeat: 962 / 230

Going ahead to step 8:
If we divide 962 by 230, we get 4 and a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 375824.0
Subtracting 920 from 962 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
420 divided by 230 is 1 with a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 375824.1
Subtract 230 from 420 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 10:
1900 divided by 230 is 8 with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 375824.18
The remainder is 60 after subtracting 1840 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
230 can be fit into 600 2 times, resulting in a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 375824.182
The remainder is 140 after subtracting 460 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 12:
230 goes into 1400 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 375824.1826
If we subtract 1380 from 1400, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
When dividing 200 by 230, we get 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 375824.1826
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 14:
2000 divided by 230 is 8 with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 375824.182608
Deduct 1840 from 2000 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
1600 divided by 230 is 6 with a remainder of 220.
Write down 6 as next digit of the result. 
Result so far: 375824.1826086
If we subtract 1380 from 1600, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 16:
The number 230 fits into 2200 9 times, leaving a remainder of 130.
The next digit of our result is 9. 
Result so far: 375824.18260869
If we subtract 2070 from 2200, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

After the division, we end up with 375824.18260869 and a remainder of 1.3e-07.
