We look at the division of 613461 by 21 
Our goal is to divide 613461 by 21.

Let's proceed to step 1:
The number 21 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 21

Moving on to step 2:
21 goes into 61 2 times with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 42 from 61 to get 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 21

Advancing to step 3:
193 divided by 21 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 29.0
If we subtract 189 from 193, we get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 21

On to step 4:
If we divide 44 by 21, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 292.0
If we subtract 42 from 44, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 21

Advancing to step 5:
26 divided by 21 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 2921.0
Subtracting 21 from 26 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 21

Going ahead to step 6:
If we divide 51 by 21, we get 2 and a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 29212.0
If we subtract 42 from 51, 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.

Let's proceed to step 7:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 29212.4
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 29212.42
If we subtract 42 from 60, we 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.

Step 9:
180 divided by 21 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 29212.428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
If we divide 120 by 21, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 29212.4285
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.

Let's proceed to step 11:
21 goes into 150 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 29212.42857
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
The number 21 fits into 30 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 29212.428571
Deduct 21 from 30 and we're left 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.

Advancing to step 13:
When dividing 90 by 21, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 29212.4285714
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 14:
60 divided by 21 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 29212.42857142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 29212.42857142 with a remaining 1.8e-08.
