We're dividing 23925309 by 657 
We want to figure out the number of times 23925309 can be divided by 657.

Step 1:
The number 657 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 657

Moving on to step 2:
23 divided by 657 is 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 657

Moving on to step 3:
When dividing 239 by 657, we get 0 with a remainder of 239.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 239, we get 239.
Grab the next digit (2) from the dividend, add it to 239, then carry on: 2392 / 657

Step 4:
If we divide 2392 by 657, we get 3 and a remainder of 421.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 1971 away from 2392, we end up with 421.
Grab the next digit (5) from the dividend, add it to 421, then carry on: 4215 / 657

On to step 5:
657 goes into 4215 6 times with a remainder of 273.
The next digit of our result is 6. 
Result so far: 36.0
Subtract 3942 from 4215 to get 273.
Append the next digit (3) from the dividend to 273 and continue with: 2733 / 657

On to step 6:
657 can be fit into 2733 4 times, resulting in a remainder of 105.
Record the quotient 4 as the next digit in the result. 
Result so far: 364.0
Subtracting 2628 from 2733 leaves us with 105.
Append the next digit (0) from the dividend to 105 and continue with: 1050 / 657

On to step 7:
657 goes into 1050 1 times with a remainder of 393.
The next digit of our result is 1. 
Result so far: 3641.0
If we take 657 away from 1050, we end up with 393.
Bring next digit (9) of the dividend behind the 393 and repeat the process: 3939 / 657

On to step 8:
657 goes into 3939 5 times with a remainder of 654.
Use 5 as the next digit of our solution. 
Result so far: 36415.0
If we subtract 3285 from 3939, we get 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Step 9:
6540 divided by 657 is 9 with a remainder of 627.
Use 9 as the next digit of our solution. 
Result so far: 36415.9
If we take 5913 away from 6540, we end up with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

On to step 10:
The number 657 fits into 6270 9 times, leaving a remainder of 357.
Record the quotient 9 as the next digit in the result. 
Result so far: 36415.99
The remainder is 357 after subtracting 5913 from 6270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

In conclusion, the division gives 36415.99 with a balance of 0.357.
