521736 divided by 86 
Our goal is to divide 521736 by 86.

Advancing to step 1:
The number 86 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 86

Moving on to step 2:
If we divide 52 by 86, we get 0 and a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 86

Let's proceed to step 3:
86 goes into 521 6 times with a remainder of 5.
The next digit of our result is 6. 
Result so far: 6.0
If we take 516 away from 521, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 86

Going ahead to step 4:
When dividing 57 by 86, we get 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
The remainder is 57 after subtracting 0 from 57.
Fetch the next digit (3) from the dividend, attach it to 57 and continue: 573 / 86

Moving on to step 5:
If we divide 573 by 86, we get 6 and a remainder of 57.
The next digit of our result is 6. 
Result so far: 606.0
If we take 516 away from 573, we end up with 57.
Grab the next digit (6) from the dividend, add it to 57, then carry on: 576 / 86

On to step 6:
576 divided by 86 is 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 6066.0
Deduct 516 from 576 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 7:
600 divided by 86 is 6 with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 6066.6
Subtracting 516 from 600 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 8:
840 divided by 86 is 9 with a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 6066.69
Subtract 774 from 840 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
If we divide 660 by 86, we get 7 and a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 6066.697
If we subtract 602 from 660, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
If we divide 580 by 86, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 6066.6976
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
When dividing 640 by 86, we get 7 with a remainder of 38.
The next digit of our result is 7. 
Result so far: 6066.69767
If we take 602 away from 640, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 6066.697674
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
If we divide 360 by 86, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 6066.6976744
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 6066.6976744, and the remainder is 1.6e-07.
