Let's divide 55813397 by 391
We want to figure out the number of times 55813397 can be divided by 391.

Advancing to step 1:
391 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 391

Advancing to step 2:
If we divide 55 by 391, we get 0 and a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Include the next digit (8) from the dividend after 55, then repeat: 558 / 391

Step 3:
391 can be fit into 558 1 times, resulting in a remainder of 167.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 391 from 558, we get 167.
Grab the next digit (1) from the dividend, add it to 167, then carry on: 1671 / 391

Moving on to step 4:
1671 divided by 391 is 4 with a remainder of 107.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 1564 from 1671, we get 107.
Append the next digit (3) from the dividend to 107 and continue with: 1073 / 391

Advancing to step 5:
391 can be fit into 1073 2 times, resulting in a remainder of 291.
Write down 2 as next digit of the result. 
Result so far: 142.0
The remainder is 291 after subtracting 782 from 1073.
Grab the next digit (3) from the dividend, add it to 291, then carry on: 2913 / 391

On to step 6:
If we divide 2913 by 391, we get 7 and a remainder of 176.
Write down 7 as next digit of the result. 
Result so far: 1427.0
If we subtract 2737 from 2913, we get 176.
Fetch the next digit (9) from the dividend, attach it to 176 and continue: 1769 / 391

Moving on to step 7:
When dividing 1769 by 391, we get 4 with a remainder of 205.
The number 4 becomes the next digit in our result. 
Result so far: 14274.0
If we take 1564 away from 1769, we end up with 205.
Fetch the next digit (7) from the dividend, attach it to 205 and continue: 2057 / 391

On to step 8:
If we divide 2057 by 391, we get 5 and a remainder of 102.
Record the quotient 5 as the next digit in the result. 
Result so far: 142745.0
Subtracting 1955 from 2057 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 9:
When dividing 1020 by 391, we get 2 with a remainder of 238.
Record the quotient 2 as the next digit in the result. 
Result so far: 142745.2
If we take 782 away from 1020, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 10:
391 goes into 2380 6 times with a remainder of 34.
The next digit of our result is 6. 
Result so far: 142745.26
Subtracting 2346 from 2380 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
391 can be fit into 340 0 times, resulting in a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 142745.26
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 12:
391 goes into 3400 8 times with a remainder of 272.
Use 8 as the next digit of our solution. 
Result so far: 142745.2608
Subtracting 3128 from 3400 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 13:
391 can be fit into 2720 6 times, resulting in a remainder of 374.
The number 6 becomes the next digit in our result. 
Result so far: 142745.26086
Deduct 2346 from 2720 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 14:
When dividing 3740 by 391, we get 9 with a remainder of 221.
The number 9 becomes the next digit in our result. 
Result so far: 142745.260869
If we take 3519 away from 3740, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Step 15:
If we divide 2210 by 391, we get 5 and a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 142745.2608695
If we subtract 1955 from 2210, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 16:
The number 391 fits into 2550 6 times, leaving a remainder of 204.
Put 6 as the next digit of the answer. 
Result so far: 142745.26086956
Subtract 2346 from 2550 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The quotient of the division is 142745.26086956, and the remainder is 2.04e-07.
