Let's divide 87128734 by 86
We're looking to find how many times 86 goes into 87128734.

Let's proceed to step 1:
If we divide 8 by 86, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 86

Moving on to step 2:
86 can be fit into 87 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we take 86 away from 87, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 86

Advancing to step 3:
If we divide 11 by 86, we get 0 and a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 86

Moving on to step 4:
When dividing 112 by 86, we get 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Subtracting 86 from 112 leaves us with 26.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 86

On to step 5:
If we divide 268 by 86, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 1013.0
Subtracting 258 from 268 leaves us with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 86

On to step 6:
86 goes into 107 1 times with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 10131.0
If we take 86 away from 107, we end up with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 86

On to step 7:
The number 86 fits into 213 2 times, leaving a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 101312.0
If we subtract 172 from 213, we get 41.
Take the next digit (4) from the dividend and append it to 41, then repeat: 414 / 86

Moving on to step 8:
86 goes into 414 4 times with a remainder of 70.
The next digit of our result is 4. 
Result so far: 1013124.0
If we take 344 away from 414, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
The number 86 fits into 700 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1013124.8
Deduct 688 from 700 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
The number 86 fits into 120 1 times, leaving a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1013124.81
If we take 86 away from 120, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
340 divided by 86 is 3 with a remainder of 82.
The next digit of our result is 3. 
Result so far: 1013124.813
If we take 258 away from 340, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 12:
86 goes into 820 9 times with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 1013124.8139
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
If we divide 460 by 86, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 1013124.81395
If we subtract 430 from 460, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
When dividing 300 by 86, we get 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 1013124.813953
Deduct 258 from 300 and we're left 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.

Step 15:
If we divide 420 by 86, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 1013124.8139534
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 16:
If we divide 760 by 86, we get 8 and a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 1013124.81395348
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 1013124.81395348 with a remaining 7.2e-08.
