We're dividing 698853 by 21 
We want to figure out the number of times 698853 can be divided by 21.

Step 1:
21 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 21

On to 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 subtract 63 from 69, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 21

Going ahead to step 3:
If we divide 68 by 21, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtract 63 from 68 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 21

Step 4:
21 goes into 58 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 332.0
If we subtract 42 from 58, we get 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 21

Advancing to step 5:
21 can be fit into 165 7 times, resulting in a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 3327.0
Subtracting 147 from 165 leaves us with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 21

Going ahead to step 6:
The number 21 fits into 183 8 times, leaving a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 33278.0
If we take 168 away from 183, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
If we divide 150 by 21, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 33278.7
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.

Going ahead to step 8:
30 divided by 21 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 33278.71
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.

Going ahead to step 9:
The number 21 fits into 90 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 33278.714
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.

Advancing to step 10:
21 can be fit into 60 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 33278.7142
If we take 42 away from 60, we end up 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.

Going ahead to step 11:
The number 21 fits into 180 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 33278.71428
Deduct 168 from 180 and we're left 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.

Step 12:
The number 21 fits into 120 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 33278.714285
If we subtract 105 from 120, we get 15.
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 13:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 33278.7142857
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
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: 33278.71428571
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 33278.71428571 with a balance of 9e-09.
