We look at the division of 61872329 by 621 
We're looking to find how many times 621 goes into 61872329.

Going ahead to step 1:
When dividing 6 by 621, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 621

Advancing to step 2:
61 divided by 621 is 0 with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 621

Moving on to step 3:
If we divide 618 by 621, we get 0 and a remainder of 618.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 618 after subtracting 0 from 618.
Append the next digit (7) from the dividend to 618 and continue with: 6187 / 621

Going ahead to step 4:
The number 621 fits into 6187 9 times, leaving a remainder of 598.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 5589 from 6187 leaves us with 598.
Include the next digit (2) from the dividend after 598, then repeat: 5982 / 621

Going ahead to step 5:
621 can be fit into 5982 9 times, resulting in a remainder of 393.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we subtract 5589 from 5982, we get 393.
Append the next digit (3) from the dividend to 393 and continue with: 3933 / 621

Step 6:
If we divide 3933 by 621, we get 6 and a remainder of 207.
Record the quotient 6 as the next digit in the result. 
Result so far: 996.0
Subtracting 3726 from 3933 leaves us with 207.
Grab the next digit (2) from the dividend, add it to 207, then carry on: 2072 / 621

Going ahead to step 7:
If we divide 2072 by 621, we get 3 and a remainder of 209.
Put 3 as the next digit of the answer. 
Result so far: 9963.0
Deduct 1863 from 2072 and we're left with 209.
Bring next digit (9) of the dividend behind the 209 and repeat the process: 2099 / 621

Let's proceed to step 8:
621 goes into 2099 3 times with a remainder of 236.
Write down 3 as next digit of the result. 
Result so far: 99633.0
Subtract 1863 from 2099 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 9:
621 can be fit into 2360 3 times, resulting in a remainder of 497.
The number 3 becomes the next digit in our result. 
Result so far: 99633.3
Subtracting 1863 from 2360 leaves us with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Moving on to step 10:
621 goes into 4970 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 99633.38
The remainder is 2 after subtracting 4968 from 4970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
The number 621 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 99633.38
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
If we divide 200 by 621, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 99633.38
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 99633.38, and the remainder is 0.002.
