We're dividing 69874349 by 86 
Our goal is to divide 69874349 by 86.

Let's proceed to step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 86

Going ahead to step 2:
When dividing 69 by 86, we get 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 86

Step 3:
When dividing 698 by 86, we get 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 10 after subtracting 688 from 698.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 86

Going ahead to step 4:
If we divide 107 by 86, we get 1 and a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtract 86 from 107 to get 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 86

Advancing to step 5:
When dividing 214 by 86, we get 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 812.0
If we take 172 away from 214, we end up with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 86

Going ahead to step 6:
The number 86 fits into 423 4 times, leaving a remainder of 79.
The number 4 becomes the next digit in our result. 
Result so far: 8124.0
Subtracting 344 from 423 leaves us with 79.
Take the next digit (4) from the dividend and append it to 79, then repeat: 794 / 86

Step 7:
When dividing 794 by 86, we get 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 81249.0
Deduct 774 from 794 and we're left with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 86

On to step 8:
When dividing 209 by 86, we get 2 with a remainder of 37.
The next digit of our result is 2. 
Result so far: 812492.0
The remainder is 37 after subtracting 172 from 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
86 goes into 370 4 times with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 812492.4
Subtracting 344 from 370 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
86 goes into 260 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 812492.43
Deduct 258 from 260 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
20 divided by 86 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 812492.43
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
If we divide 200 by 86, we get 2 and a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 812492.4302
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
280 divided by 86 is 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 812492.43023
The remainder is 22 after subtracting 258 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
220 divided by 86 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 812492.430232
If we take 172 away from 220, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 15:
The number 86 fits into 480 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 812492.4302325
Deduct 430 from 480 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 16:
500 divided by 86 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 812492.43023255
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 812492.43023255 with a remainder of 7e-08.
