We're dividing 40917374 by 621 
Let's see how many times 621 fits into 40917374.

Moving on to step 1:
When dividing 4 by 621, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 621

Moving on to step 2:
The number 621 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 621

On to step 3:
If we divide 409 by 621, we get 0 and a remainder of 409.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 409 and we're left with 409.
Grab the next digit (1) from the dividend, add it to 409, then carry on: 4091 / 621

Advancing to step 4:
621 goes into 4091 6 times with a remainder of 365.
The next digit of our result is 6. 
Result so far: 6.0
If we take 3726 away from 4091, we end up with 365.
Bring next digit (7) of the dividend behind the 365 and repeat the process: 3657 / 621

Moving on to step 5:
621 can be fit into 3657 5 times, resulting in a remainder of 552.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
The remainder is 552 after subtracting 3105 from 3657.
Grab the next digit (3) from the dividend, add it to 552, then carry on: 5523 / 621

Step 6:
621 goes into 5523 8 times with a remainder of 555.
Put 8 as the next digit of the answer. 
Result so far: 658.0
Subtracting 4968 from 5523 leaves us with 555.
Take the next digit (7) from the dividend and append it to 555, then repeat: 5557 / 621

Going ahead to step 7:
5557 divided by 621 is 8 with a remainder of 589.
Use 8 as the next digit of our solution. 
Result so far: 6588.0
If we subtract 4968 from 5557, we get 589.
Grab the next digit (4) from the dividend, add it to 589, then carry on: 5894 / 621

Moving on to step 8:
If we divide 5894 by 621, we get 9 and a remainder of 305.
Record the quotient 9 as the next digit in the result. 
Result so far: 65889.0
Subtracting 5589 from 5894 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 9:
621 goes into 3050 4 times with a remainder of 566.
Use 4 as the next digit of our solution. 
Result so far: 65889.4
Deduct 2484 from 3050 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Advancing to step 10:
621 goes into 5660 9 times with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 65889.49
If we take 5589 away from 5660, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 11:
The number 621 fits into 710 1 times, leaving a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 65889.491
Subtract 621 from 710 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 12:
If we divide 890 by 621, we get 1 and a remainder of 269.
Put 1 as the next digit of the answer. 
Result so far: 65889.4911
Deduct 621 from 890 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

In conclusion, the division gives 65889.4911 with a balance of 0.00269.
