We look at the division of 21879406 by 325 
We want to figure out the number of times 21879406 can be divided by 325.

Moving on to step 1:
2 divided by 325 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 325

Moving on to step 2:
325 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 325

Going ahead to step 3:
When dividing 218 by 325, we get 0 with a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 218, we get 218.
Append the next digit (7) from the dividend to 218 and continue with: 2187 / 325

Step 4:
When dividing 2187 by 325, we get 6 with a remainder of 237.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 1950 away from 2187, we end up with 237.
Include the next digit (9) from the dividend after 237, then repeat: 2379 / 325

On to step 5:
325 can be fit into 2379 7 times, resulting in a remainder of 104.
Use 7 as the next digit of our solution. 
Result so far: 67.0
If we take 2275 away from 2379, we end up with 104.
Fetch the next digit (4) from the dividend, attach it to 104 and continue: 1044 / 325

On to step 6:
325 can be fit into 1044 3 times, resulting in a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 673.0
Deduct 975 from 1044 and we're left with 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 325

Going ahead to step 7:
When dividing 690 by 325, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 6732.0
If we take 650 away from 690, we end up with 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 325

Step 8:
The number 325 fits into 406 1 times, leaving a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 67321.0
Deduct 325 from 406 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 9:
When dividing 810 by 325, we get 2 with a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 67321.2
Subtract 650 from 810 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 10:
1600 divided by 325 is 4 with a remainder of 300.
Put 4 as the next digit of the answer. 
Result so far: 67321.24
Subtract 1300 from 1600 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
The number 325 fits into 3000 9 times, leaving a remainder of 75.
Use 9 as the next digit of our solution. 
Result so far: 67321.249
The remainder is 75 after subtracting 2925 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
325 goes into 750 2 times with a remainder of 100.
The number 2 becomes the next digit in our result. 
Result so far: 67321.2492
Subtracting 650 from 750 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
1000 divided by 325 is 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 67321.24923
Subtracting 975 from 1000 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 14:
325 can be fit into 250 0 times, resulting in a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 67321.24923
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 15:
325 goes into 2500 7 times with a remainder of 225.
Write down 7 as next digit of the result. 
Result so far: 67321.2492307
Subtracting 2275 from 2500 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 16:
2250 divided by 325 is 6 with a remainder of 300.
Put 6 as the next digit of the answer. 
Result so far: 67321.24923076
The remainder is 300 after subtracting 1950 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 67321.24923076 with a remaining 3e-07.
