We look at the division of 784969 by 21 
Our goal is to divide 784969 by 21.

Step 1:
21 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 21

Moving on to step 2:
The number 21 fits into 78 3 times, leaving a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 63 from 78 and we're left with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 21

Step 3:
21 can be fit into 154 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 147 from 154, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 21

Moving on to step 4:
21 can be fit into 79 3 times, resulting in a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 373.0
Subtract 63 from 79 to get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 21

Let's proceed to step 5:
If we divide 166 by 21, we get 7 and a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 3737.0
If we take 147 away from 166, we end up with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 21

Let's proceed to step 6:
199 divided by 21 is 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 37379.0
If we subtract 189 from 199, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 21, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 37379.4
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
When dividing 160 by 21, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 37379.47
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 37379.476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
40 divided by 21 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 37379.4761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
190 divided by 21 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 37379.47619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 12:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 37379.47619
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 37379.4761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
160 divided by 21 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 37379.47619047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 37379.47619047 with a remaining 1.3e-08.
