We're dividing 57428192 by 621 
We want to figure out the number of times 57428192 can be divided by 621.

Step 1:
The number 621 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 621

Advancing to step 2:
57 divided by 621 is 0 with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Append the next digit (4) from the dividend to 57 and continue with: 574 / 621

Advancing to step 3:
621 goes into 574 0 times with a remainder of 574.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 574, we end up with 574.
Fetch the next digit (2) from the dividend, attach it to 574 and continue: 5742 / 621

Going ahead to step 4:
If we divide 5742 by 621, we get 9 and a remainder of 153.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 5589 from 5742 and we're left with 153.
Take the next digit (8) from the dividend and append it to 153, then repeat: 1538 / 621

Advancing to step 5:
621 can be fit into 1538 2 times, resulting in a remainder of 296.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Subtracting 1242 from 1538 leaves us with 296.
Take the next digit (1) from the dividend and append it to 296, then repeat: 2961 / 621

Let's proceed to step 6:
When dividing 2961 by 621, we get 4 with a remainder of 477.
The next digit of our result is 4. 
Result so far: 924.0
Subtract 2484 from 2961 to get 477.
Take the next digit (9) from the dividend and append it to 477, then repeat: 4779 / 621

Going ahead to step 7:
621 goes into 4779 7 times with a remainder of 432.
Write down 7 as next digit of the result. 
Result so far: 9247.0
The remainder is 432 after subtracting 4347 from 4779.
Append the next digit (2) from the dividend to 432 and continue with: 4322 / 621

On to step 8:
If we divide 4322 by 621, we get 6 and a remainder of 596.
Record the quotient 6 as the next digit in the result. 
Result so far: 92476.0
If we take 3726 away from 4322, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 9:
If we divide 5960 by 621, we get 9 and a remainder of 371.
Record the quotient 9 as the next digit in the result. 
Result so far: 92476.9
The remainder is 371 after subtracting 5589 from 5960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

On to step 10:
3710 divided by 621 is 5 with a remainder of 605.
Write down 5 as next digit of the result. 
Result so far: 92476.95
The remainder is 605 after subtracting 3105 from 3710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Let's proceed to step 11:
The number 621 fits into 6050 9 times, leaving a remainder of 461.
Put 9 as the next digit of the answer. 
Result so far: 92476.959
If we take 5589 away from 6050, we end up with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Step 12:
If we divide 4610 by 621, we get 7 and a remainder of 263.
The number 7 becomes the next digit in our result. 
Result so far: 92476.9597
Subtract 4347 from 4610 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Moving on to step 13:
If we divide 2630 by 621, we get 4 and a remainder of 146.
Put 4 as the next digit of the answer. 
Result so far: 92476.95974
The remainder is 146 after subtracting 2484 from 2630.
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 14:
When dividing 1460 by 621, we get 2 with a remainder of 218.
The next digit of our result is 2. 
Result so far: 92476.959742
If we subtract 1242 from 1460, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 15:
If we divide 2180 by 621, we get 3 and a remainder of 317.
Use 3 as the next digit of our solution. 
Result so far: 92476.9597423
If we subtract 1863 from 2180, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Going ahead to step 16:
The number 621 fits into 3170 5 times, leaving a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 92476.95974235
Subtracting 3105 from 3170 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 92476.95974235 and a remainder of 6.5e-08.
