Let's divide 617725 by 21
Let's see how many times 21 fits into 617725.

On to step 1:
21 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 21

Advancing to step 2:
21 can be fit into 61 2 times, resulting in a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 42 from 61, we get 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 21

On to step 3:
21 can be fit into 197 9 times, resulting in a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we take 189 away from 197, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 21

Step 4:
When dividing 87 by 21, we get 4 with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 294.0
If we take 84 away from 87, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 21

On to step 5:
21 goes into 32 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 2941.0
The remainder is 11 after subtracting 21 from 32.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 21

Let's proceed to step 6:
When dividing 115 by 21, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 29415.0
Subtract 105 from 115 to 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:
100 divided by 21 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 29415.4
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 8:
160 divided by 21 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 29415.47
Deduct 147 from 160 and we're left 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:
130 divided by 21 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 29415.476
Subtract 126 from 130 to 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.

Step 10:
21 goes into 40 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 29415.4761
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.

Step 11:
21 goes into 190 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 29415.47619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
When dividing 10 by 21, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 29415.47619
If we subtract 0 from 10, 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 13:
21 goes into 100 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 29415.4761904
If we subtract 84 from 100, 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.

Step 14:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 29415.47619047
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.

The final outcome is 29415.47619047, with a leftover of 1.3e-08.
