We look at the division of 35721301 by 86 
Let's see how many times 86 fits into 35721301.

Step 1:
3 divided by 86 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 86

Step 2:
86 goes into 35 0 times with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 86

On to step 3:
86 goes into 357 4 times with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 344 from 357 and we're left with 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 86

Advancing to step 4:
86 can be fit into 132 1 times, resulting in a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
The remainder is 46 after subtracting 86 from 132.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 86

Moving on to step 5:
The number 86 fits into 461 5 times, leaving a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 415.0
Subtract 430 from 461 to get 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 86

On to step 6:
86 can be fit into 313 3 times, resulting in a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 4153.0
Subtract 258 from 313 to get 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 86

Step 7:
The number 86 fits into 550 6 times, leaving a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 41536.0
Subtract 516 from 550 to get 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 86

Moving on to step 8:
341 divided by 86 is 3 with a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 415363.0
If we subtract 258 from 341, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 9:
When dividing 830 by 86, we get 9 with a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 415363.9
If we take 774 away from 830, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
560 divided by 86 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 415363.96
Deduct 516 from 560 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 415363.965
If we take 430 away from 440, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
100 divided by 86 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 415363.9651
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
When dividing 140 by 86, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 415363.96511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 415363.96511 with a remaining 5.4e-05.
