We're dividing 83605526 by 521 
Our goal is to divide 83605526 by 521.

Step 1:
When dividing 8 by 521, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 521

Going ahead to step 2:
The number 521 fits into 83 0 times, leaving a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Take the next digit (6) from the dividend and append it to 83, then repeat: 836 / 521

On to step 3:
521 can be fit into 836 1 times, resulting in a remainder of 315.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 521 away from 836, we end up with 315.
Fetch the next digit (0) from the dividend, attach it to 315 and continue: 3150 / 521

Advancing to step 4:
3150 divided by 521 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 3126 from 3150 to get 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 521

Moving on to step 5:
521 goes into 245 0 times with a remainder of 245.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
The remainder is 245 after subtracting 0 from 245.
Include the next digit (5) from the dividend after 245, then repeat: 2455 / 521

Moving on to step 6:
The number 521 fits into 2455 4 times, leaving a remainder of 371.
Write down 4 as next digit of the result. 
Result so far: 1604.0
Subtracting 2084 from 2455 leaves us with 371.
Bring next digit (2) of the dividend behind the 371 and repeat the process: 3712 / 521

Step 7:
3712 divided by 521 is 7 with a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 16047.0
Subtracting 3647 from 3712 leaves us with 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 521

Moving on to step 8:
656 divided by 521 is 1 with a remainder of 135.
The number 1 becomes the next digit in our result. 
Result so far: 160471.0
If we subtract 521 from 656, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 9:
521 can be fit into 1350 2 times, resulting in a remainder of 308.
Record the quotient 2 as the next digit in the result. 
Result so far: 160471.2
Subtracting 1042 from 1350 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 10:
When dividing 3080 by 521, we get 5 with a remainder of 475.
Use 5 as the next digit of our solution. 
Result so far: 160471.25
Deduct 2605 from 3080 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

On to step 11:
521 can be fit into 4750 9 times, resulting in a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 160471.259
Subtracting 4689 from 4750 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
If we divide 610 by 521, we get 1 and a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 160471.2591
Subtracting 521 from 610 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 13:
If we divide 890 by 521, we get 1 and a remainder of 369.
The next digit of our result is 1. 
Result so far: 160471.25911
Deduct 521 from 890 and we're left with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

The final result is 160471.25911 with a remainder of 0.000369.
