We're dividing 20999770 by 52 
We want to figure out the number of times 20999770 can be divided by 52.

On to step 1:
52 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 52

On to step 2:
52 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 52

Step 3:
When dividing 209 by 52, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 1 after subtracting 208 from 209.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 52

Moving on to step 4:
52 can be fit into 19 0 times, resulting in a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 52

Going ahead to step 5:
52 goes into 199 3 times with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 403.0
Deduct 156 from 199 and we're left with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 52

Moving on to step 6:
When dividing 437 by 52, we get 8 with a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 4038.0
Subtracting 416 from 437 leaves us with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 52

Going ahead to step 7:
52 can be fit into 217 4 times, resulting in a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 40384.0
The remainder is 9 after subtracting 208 from 217.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 52

Advancing to step 8:
When dividing 90 by 52, we get 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 403841.0
Deduct 52 from 90 and we're left 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 9:
52 can be fit into 380 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 403841.7
Subtracting 364 from 380 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
If we divide 160 by 52, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 403841.73
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
The number 52 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 403841.73
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
52 can be fit into 400 7 times, resulting in a remainder of 36.
The next digit of our result is 7. 
Result so far: 403841.7307
If we take 364 away from 400, we end up 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.

Going ahead to step 13:
52 goes into 360 6 times with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 403841.73076
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
52 can be fit into 480 9 times, resulting in a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 403841.730769
If we subtract 468 from 480, we 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.

Going ahead to step 15:
If we divide 120 by 52, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 403841.7307692
If we subtract 104 from 120, we 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.

On to step 16:
52 can be fit into 160 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 403841.73076923
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 403841.73076923 and a remainder of 4e-09.
