We look at the division of 82960884 by 21 
We want to figure out the number of times 82960884 can be divided by 21.

Going ahead to step 1:
The number 21 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 21

Moving on to step 2:
The number 21 fits into 82 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 3.0
If we take 63 away from 82, we end up with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 21

Advancing to step 3:
If we divide 199 by 21, we get 9 and a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtract 189 from 199 to get 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 21

Moving on to step 4:
106 divided by 21 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 395.0
The remainder is 1 after subtracting 105 from 106.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 21

On to step 5:
If we divide 10 by 21, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3950.0
Subtract 0 from 10 to get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 21

On to step 6:
21 can be fit into 108 5 times, resulting in a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 39505.0
Deduct 105 from 108 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 21

On to step 7:
If we divide 38 by 21, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 395051.0
Deduct 21 from 38 and we're left with 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 21

Let's proceed to step 8:
The number 21 fits into 174 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 3950518.0
If we take 168 away from 174, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
If we divide 60 by 21, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 3950518.2
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
If we divide 180 by 21, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 3950518.28
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
When dividing 120 by 21, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 3950518.285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 3950518.2857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 13:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 3950518.28571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
21 can be fit into 90 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 3950518.285714
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 15:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 3950518.2857142
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 16:
When dividing 180 by 21, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 3950518.28571428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 3950518.28571428 and a remainder of 1.2e-08.
