793647 divided by 21 
Let's see how many times 21 fits into 793647.

Advancing to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 21

Going ahead to step 2:
If we divide 79 by 21, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 63 away from 79, we end up with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 21

Going ahead to step 3:
163 divided by 21 is 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we subtract 147 from 163, we get 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 21

Let's proceed to step 4:
When dividing 166 by 21, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 377.0
If we take 147 away from 166, we end up with 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 21

Moving on to step 5:
The number 21 fits into 194 9 times, leaving a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 3779.0
If we take 189 away from 194, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 21

Advancing to step 6:
57 divided by 21 is 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 37792.0
If we subtract 42 from 57, 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.

Step 7:
150 divided by 21 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 37792.7
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.

Going ahead to step 8:
21 goes into 30 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 37792.71
Subtracting 21 from 30 leaves us 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.

Step 9:
21 goes into 90 4 times with a remainder of 6.
The next digit of our result is 4. 
Result so far: 37792.714
The remainder is 6 after subtracting 84 from 90.
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 10:
If we divide 60 by 21, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 37792.7142
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.

On to step 11:
180 divided by 21 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 37792.71428
Subtracting 168 from 180 leaves us 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:
If we divide 120 by 21, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 37792.714285
If we take 105 away from 120, 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.

Advancing to step 13:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 37792.7142857
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.

Going ahead to step 14:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 37792.71428571
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.

The final result is 37792.71428571 with a remainder of 9e-09.
