We're dividing 56728615 by 86 
We want to figure out the number of times 56728615 can be divided by 86.

Advancing to step 1:
5 divided by 86 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 86

Moving on to step 2:
86 goes into 56 0 times with a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 56 after subtracting 0 from 56.
Fetch the next digit (7) from the dividend, attach it to 56 and continue: 567 / 86

Moving on to step 3:
The number 86 fits into 567 6 times, leaving a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 516 away from 567, we end up with 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 86

Advancing to step 4:
86 can be fit into 512 5 times, resulting in a remainder of 82.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
The remainder is 82 after subtracting 430 from 512.
Take the next digit (8) from the dividend and append it to 82, then repeat: 828 / 86

Moving on to step 5:
If we divide 828 by 86, we get 9 and a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 659.0
The remainder is 54 after subtracting 774 from 828.
Bring next digit (6) of the dividend behind the 54 and repeat the process: 546 / 86

Going ahead to step 6:
When dividing 546 by 86, we get 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 6596.0
The remainder is 30 after subtracting 516 from 546.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 86

Step 7:
The number 86 fits into 301 3 times, leaving a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 65963.0
Deduct 258 from 301 and we're left with 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 86

On to step 8:
86 can be fit into 435 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 659635.0
If we subtract 430 from 435, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
86 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 659635.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
500 divided by 86 is 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 659635.05
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
If we divide 700 by 86, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 659635.058
Subtract 688 from 700 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
86 can be fit into 120 1 times, resulting in a remainder of 34.
The next digit of our result is 1. 
Result so far: 659635.0581
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
The number 86 fits into 340 3 times, leaving a remainder of 82.
The next digit of our result is 3. 
Result so far: 659635.05813
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.

Going ahead to step 14:
86 goes into 820 9 times with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 659635.058139
Deduct 774 from 820 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 15:
460 divided by 86 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 659635.0581395
Subtract 430 from 460 to 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.

On to step 16:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 659635.05813953
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 659635.05813953, and the remainder is 4.2e-08.
