We look at the division of 699479 by 21 
We want to divide 699479 by 21.

Advancing to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 21

Step 2:
69 divided by 21 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 63 away from 69, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 21

Moving on to step 3:
If we divide 69 by 21, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 33.0
Subtract 63 from 69 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 21

Let's proceed to step 4:
21 can be fit into 64 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 333.0
Deduct 63 from 64 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 21

On to step 5:
The number 21 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 3330.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 21

Advancing to step 6:
The number 21 fits into 179 8 times, leaving a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 33308.0
If we take 168 away from 179, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 21, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 33308.5
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 33308.52
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
21 goes into 80 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 33308.523
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
If we divide 170 by 21, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 33308.5238
Subtract 168 from 170 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
When dividing 20 by 21, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 33308.5238
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
21 goes into 200 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 33308.523809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 13:
When dividing 110 by 21, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 33308.5238095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 33308.52380952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 33308.52380952 and a remainder of 8e-09.
