607159 divided by 21 
Let's see how many times 21 fits into 607159.

Going ahead to step 1:
6 divided by 21 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 21

Advancing to step 2:
21 goes into 60 2 times with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 18 after subtracting 42 from 60.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 21

Moving on to step 3:
When dividing 187 by 21, we get 8 with a remainder of 19.
The next digit of our result is 8. 
Result so far: 28.0
Deduct 168 from 187 and we're left with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 21

Going ahead to step 4:
The number 21 fits into 191 9 times, leaving a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 289.0
Subtracting 189 from 191 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 21

Moving on to step 5:
21 can be fit into 25 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 2891.0
Subtract 21 from 25 to get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 21

On to step 6:
21 can be fit into 49 2 times, resulting in a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 28912.0
If we take 42 away from 49, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
The number 21 fits into 70 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 28912.3
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
21 can be fit into 70 3 times, resulting in a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 28912.33
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 28912.33 with a balance of 0.007.
