796231 ÷ 21 
We're looking to find how many times 21 goes into 796231.

Moving on to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 21

Going ahead to step 2:
The number 21 fits into 79 3 times, leaving a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 63 from 79 and we're left with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 21

On to step 3:
21 goes into 166 7 times with a remainder of 19.
The next digit of our result is 7. 
Result so far: 37.0
Subtract 147 from 166 to get 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 21

Advancing to step 4:
If we divide 192 by 21, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 379.0
Subtract 189 from 192 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 21

On to step 5:
33 divided by 21 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 3791.0
If we subtract 21 from 33, we get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 21

On to step 6:
When dividing 121 by 21, we get 5 with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 37915.0
If we subtract 105 from 121, we 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.

On to step 7:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 37915.7
Subtracting 147 from 160 leaves us 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.

Let's proceed to step 8:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 37915.76
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 21, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 37915.761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 10:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 37915.7619
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 11:
21 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 37915.7619
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.

Going ahead to step 12:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 37915.761904
Subtracting 84 from 100 leaves us with 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 13:
21 goes into 160 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 37915.7619047
The remainder is 13 after subtracting 147 from 160.
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 14:
130 divided by 21 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 37915.76190476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 37915.76190476 with a remaining 4e-09.
