We divide 21013522 by 53
We want to divide 21013522 by 53.

Going ahead to step 1:
When dividing 2 by 53, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 53

Moving on to step 2:
21 divided by 53 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 53

Advancing to step 3:
If we divide 210 by 53, we get 3 and a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 51 after subtracting 159 from 210.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 53

Step 4:
511 divided by 53 is 9 with a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Deduct 477 from 511 and we're left with 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 53

On to step 5:
When dividing 343 by 53, we get 6 with a remainder of 25.
The next digit of our result is 6. 
Result so far: 396.0
Deduct 318 from 343 and we're left with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 53

Advancing to step 6:
If we divide 255 by 53, we get 4 and a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 3964.0
Subtract 212 from 255 to get 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 53

Moving on to step 7:
If we divide 432 by 53, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 39648.0
Subtracting 424 from 432 leaves us with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 53

Going ahead to step 8:
If we divide 82 by 53, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 396481.0
If we take 53 away from 82, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
If we divide 290 by 53, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 396481.5
If we subtract 265 from 290, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
If we divide 250 by 53, we get 4 and a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 396481.54
Subtracting 212 from 250 leaves us 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.

Going ahead to step 11:
When dividing 380 by 53, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 396481.547
If we subtract 371 from 380, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 12:
90 divided by 53 is 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 396481.5471
Subtract 53 from 90 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 13:
53 can be fit into 370 6 times, resulting in a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 396481.54716
If we take 318 away from 370, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 14:
The number 53 fits into 520 9 times, leaving a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 396481.547169
The remainder is 43 after subtracting 477 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 15:
If we divide 430 by 53, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 396481.5471698
Subtract 424 from 430 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 16:
53 goes into 60 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 396481.54716981
Deduct 53 from 60 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 396481.54716981 with a remainder of 7e-09.
