Let's divide 621770 by 74
We want to divide 621770 by 74.

Advancing to step 1:
74 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 74

Moving on to step 2:
The number 74 fits into 62 0 times, leaving a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 74

Let's proceed to step 3:
When dividing 621 by 74, we get 8 with a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 592 from 621, we get 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 74

On to step 4:
74 can be fit into 297 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtract 296 from 297 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 74

Let's proceed to step 5:
17 divided by 74 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 840.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 74

Let's proceed to step 6:
When dividing 170 by 74, we get 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 8402.0
Deduct 148 from 170 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
220 divided by 74 is 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 8402.2
If we take 148 away from 220, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 8:
74 can be fit into 720 9 times, resulting in a remainder of 54.
The next digit of our result is 9. 
Result so far: 8402.29
The remainder is 54 after subtracting 666 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
When dividing 540 by 74, we get 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 8402.297
Deduct 518 from 540 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
74 can be fit into 220 2 times, resulting in a remainder of 72.
The next digit of our result is 2. 
Result so far: 8402.2972
Subtracting 148 from 220 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
720 divided by 74 is 9 with a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 8402.29729
Subtracting 666 from 720 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 12:
When dividing 540 by 74, we get 7 with a remainder of 22.
The next digit of our result is 7. 
Result so far: 8402.297297
If we take 518 away from 540, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
220 divided by 74 is 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 8402.2972972
Subtract 148 from 220 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
The number 74 fits into 720 9 times, leaving a remainder of 54.
The next digit of our result is 9. 
Result so far: 8402.29729729
Deduct 666 from 720 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 8402.29729729 with a remainder of 5.4e-08.
