Let's divide 20552297 by 391
We want to figure out the number of times 20552297 can be divided by 391.

On to step 1:
If we divide 2 by 391, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our 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 / 391

Advancing to step 2:
When dividing 20 by 391, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 391

Advancing to step 3:
391 can be fit into 205 0 times, resulting in a remainder of 205.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 205 to get 205.
Grab the next digit (5) from the dividend, add it to 205, then carry on: 2055 / 391

Going ahead to step 4:
The number 391 fits into 2055 5 times, leaving a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 100 after subtracting 1955 from 2055.
Grab the next digit (2) from the dividend, add it to 100, then carry on: 1002 / 391

Step 5:
1002 divided by 391 is 2 with a remainder of 220.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Deduct 782 from 1002 and we're left with 220.
Take the next digit (2) from the dividend and append it to 220, then repeat: 2202 / 391

Advancing to step 6:
If we divide 2202 by 391, we get 5 and a remainder of 247.
Use 5 as the next digit of our solution. 
Result so far: 525.0
Subtracting 1955 from 2202 leaves us with 247.
Bring next digit (9) of the dividend behind the 247 and repeat the process: 2479 / 391

Going ahead to step 7:
The number 391 fits into 2479 6 times, leaving a remainder of 133.
The next digit of our result is 6. 
Result so far: 5256.0
Deduct 2346 from 2479 and we're left with 133.
Append the next digit (7) from the dividend to 133 and continue with: 1337 / 391

Advancing to step 8:
391 can be fit into 1337 3 times, resulting in a remainder of 164.
The number 3 becomes the next digit in our result. 
Result so far: 52563.0
The remainder is 164 after subtracting 1173 from 1337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 9:
1640 divided by 391 is 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 52563.4
If we take 1564 away from 1640, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
391 can be fit into 760 1 times, resulting in a remainder of 369.
The next digit of our result is 1. 
Result so far: 52563.41
The remainder is 369 after subtracting 391 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Moving on to step 11:
If we divide 3690 by 391, we get 9 and a remainder of 171.
Record the quotient 9 as the next digit in the result. 
Result so far: 52563.419
If we take 3519 away from 3690, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 12:
If we divide 1710 by 391, we get 4 and a remainder of 146.
Record the quotient 4 as the next digit in the result. 
Result so far: 52563.4194
If we take 1564 away from 1710, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 13:
If we divide 1460 by 391, we get 3 and a remainder of 287.
Put 3 as the next digit of the answer. 
Result so far: 52563.41943
If we take 1173 away from 1460, we end up with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Step 14:
The number 391 fits into 2870 7 times, leaving a remainder of 133.
The number 7 becomes the next digit in our result. 
Result so far: 52563.419437
Subtracting 2737 from 2870 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 15:
391 can be fit into 1330 3 times, resulting in a remainder of 157.
The number 3 becomes the next digit in our result. 
Result so far: 52563.4194373
Subtract 1173 from 1330 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 16:
When dividing 1570 by 391, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 52563.41943734
Deduct 1564 from 1570 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 52563.41943734 with a balance of 6e-09.
