57218738 divided by 621 
Our goal is to divide 57218738 by 621.

Let's proceed to step 1:
621 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 621

Advancing to step 2:
57 divided by 621 is 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Append the next digit (2) from the dividend to 57 and continue with: 572 / 621

Step 3:
621 goes into 572 0 times with a remainder of 572.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 572, we end up with 572.
Bring next digit (1) of the dividend behind the 572 and repeat the process: 5721 / 621

Let's proceed to step 4:
621 can be fit into 5721 9 times, resulting in a remainder of 132.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 5589 away from 5721, we end up with 132.
Fetch the next digit (8) from the dividend, attach it to 132 and continue: 1328 / 621

Going ahead to step 5:
621 goes into 1328 2 times with a remainder of 86.
The next digit of our result is 2. 
Result so far: 92.0
If we take 1242 away from 1328, we end up with 86.
Include the next digit (7) from the dividend after 86, then repeat: 867 / 621

On to step 6:
If we divide 867 by 621, we get 1 and a remainder of 246.
Use 1 as the next digit of our solution. 
Result so far: 921.0
If we take 621 away from 867, we end up with 246.
Grab the next digit (3) from the dividend, add it to 246, then carry on: 2463 / 621

On to step 7:
If we divide 2463 by 621, we get 3 and a remainder of 600.
The next digit of our result is 3. 
Result so far: 9213.0
Deduct 1863 from 2463 and we're left with 600.
Fetch the next digit (8) from the dividend, attach it to 600 and continue: 6008 / 621

Going ahead to step 8:
The number 621 fits into 6008 9 times, leaving a remainder of 419.
Put 9 as the next digit of the answer. 
Result so far: 92139.0
Subtracting 5589 from 6008 leaves us with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Advancing to step 9:
If we divide 4190 by 621, we get 6 and a remainder of 464.
The next digit of our result is 6. 
Result so far: 92139.6
The remainder is 464 after subtracting 3726 from 4190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 10:
When dividing 4640 by 621, we get 7 with a remainder of 293.
Record the quotient 7 as the next digit in the result. 
Result so far: 92139.67
If we take 4347 away from 4640, we end up with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Moving on to step 11:
When dividing 2930 by 621, we get 4 with a remainder of 446.
The next digit of our result is 4. 
Result so far: 92139.674
Deduct 2484 from 2930 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 12:
The number 621 fits into 4460 7 times, leaving a remainder of 113.
Record the quotient 7 as the next digit in the result. 
Result so far: 92139.6747
Subtracting 4347 from 4460 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 13:
When dividing 1130 by 621, we get 1 with a remainder of 509.
Write down 1 as next digit of the result. 
Result so far: 92139.67471
Subtract 621 from 1130 to get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

On to step 14:
If we divide 5090 by 621, we get 8 and a remainder of 122.
The number 8 becomes the next digit in our result. 
Result so far: 92139.674718
Subtracting 4968 from 5090 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 15:
If we divide 1220 by 621, we get 1 and a remainder of 599.
Put 1 as the next digit of the answer. 
Result so far: 92139.6747181
The remainder is 599 after subtracting 621 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Step 16:
621 can be fit into 5990 9 times, resulting in a remainder of 401.
Write down 9 as next digit of the result. 
Result so far: 92139.67471819
If we subtract 5589 from 5990, we get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Our division results in 92139.67471819 with a remaining 4.01e-07.
