We divide 615974 by 21
We want to figure out the number of times 615974 can be divided by 21.

Going ahead to step 1:
When dividing 6 by 21, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 21

Moving on to step 2:
If we divide 61 by 21, we get 2 and a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 42 away from 61, we end up with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 21

Step 3:
When dividing 195 by 21, we get 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtract 189 from 195 to get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 21

Advancing to step 4:
69 divided by 21 is 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 293.0
If we subtract 63 from 69, we get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 21

Moving on to step 5:
21 can be fit into 67 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 2933.0
The remainder is 4 after subtracting 63 from 67.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 21

Moving on to step 6:
If we divide 44 by 21, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 29332.0
Deduct 42 from 44 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 21, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 29332.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 29332.09
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 29332.095
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 29332.0952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
If we divide 80 by 21, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 29332.09523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 29332.095238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
21 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 29332.095238
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
When dividing 200 by 21, we get 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 29332.09523809
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 29332.09523809 with a remaining 1.1e-08.
