Let's divide 43901684 by 621
We want to divide 43901684 by 621.

Moving on to step 1:
If we divide 4 by 621, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 621

Step 2:
43 divided by 621 is 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 621

Going ahead to step 3:
439 divided by 621 is 0 with a remainder of 439.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 439, we end up with 439.
Fetch the next digit (0) from the dividend, attach it to 439 and continue: 4390 / 621

On to step 4:
621 goes into 4390 7 times with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 4347 from 4390 leaves us with 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 621

Step 5:
621 goes into 431 0 times with a remainder of 431.
Write down 0 as next digit of the result. 
Result so far: 70.0
Deduct 0 from 431 and we're left with 431.
Append the next digit (6) from the dividend to 431 and continue with: 4316 / 621

Going ahead to step 6:
If we divide 4316 by 621, we get 6 and a remainder of 590.
Put 6 as the next digit of the answer. 
Result so far: 706.0
Deduct 3726 from 4316 and we're left with 590.
Grab the next digit (8) from the dividend, add it to 590, then carry on: 5908 / 621

Moving on to step 7:
The number 621 fits into 5908 9 times, leaving a remainder of 319.
The next digit of our result is 9. 
Result so far: 7069.0
If we subtract 5589 from 5908, we get 319.
Fetch the next digit (4) from the dividend, attach it to 319 and continue: 3194 / 621

Advancing to step 8:
621 goes into 3194 5 times with a remainder of 89.
Record the quotient 5 as the next digit in the result. 
Result so far: 70695.0
The remainder is 89 after subtracting 3105 from 3194.
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 9:
621 can be fit into 890 1 times, resulting in a remainder of 269.
The number 1 becomes the next digit in our result. 
Result so far: 70695.1
The remainder is 269 after subtracting 621 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Step 10:
The number 621 fits into 2690 4 times, leaving a remainder of 206.
The number 4 becomes the next digit in our result. 
Result so far: 70695.14
Deduct 2484 from 2690 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 11:
621 can be fit into 2060 3 times, resulting in a remainder of 197.
The next digit of our result is 3. 
Result so far: 70695.143
Subtract 1863 from 2060 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 12:
When dividing 1970 by 621, we get 3 with a remainder of 107.
Write down 3 as next digit of the result. 
Result so far: 70695.1433
Deduct 1863 from 1970 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

In conclusion, the division gives 70695.1433 with a balance of 0.00107.
