We're dividing 657091 by 30 
We want to figure out the number of times 657091 can be divided by 30.

Going ahead to step 1:
When dividing 6 by 30, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 30

Step 2:
65 divided by 30 is 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 60 from 65 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 30

Advancing to step 3:
30 goes into 57 1 times with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 27 after subtracting 30 from 57.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 30

On to step 4:
When dividing 270 by 30, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 219.0
Subtract 270 from 270 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 30

On to step 5:
9 divided by 30 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 2190.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 30

On to step 6:
30 can be fit into 91 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 21903.0
The remainder is 1 after subtracting 90 from 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 30 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 21903.0
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.

Advancing to step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 21903.03
Deduct 90 from 100 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.

On to step 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 21903.033
Subtracting 90 from 100 leaves us 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.

The final outcome is 21903.033, with a leftover of 0.001.
