51607 ÷ 99 
We're looking to find how many times 99 goes into 51607.

Let's proceed to step 1:
The number 99 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 99

On to step 2:
99 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 99

Step 3:
99 goes into 516 5 times with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 495 from 516 leaves us with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 99

Going ahead to step 4:
The number 99 fits into 210 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we subtract 198 from 210, we get 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 99

On to step 5:
The number 99 fits into 127 1 times, leaving a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 521.0
Deduct 99 from 127 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 6:
99 goes into 280 2 times with a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 521.2
The remainder is 82 after subtracting 198 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 7:
If we divide 820 by 99, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 521.28
The remainder is 28 after subtracting 792 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
99 goes into 280 2 times with a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 521.282
Subtracting 198 from 280 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 9:
When dividing 820 by 99, we get 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 521.2828
If we subtract 792 from 820, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
If we divide 280 by 99, we get 2 and a remainder of 82.
Record the quotient 2 as the next digit in the result. 
Result so far: 521.28282
The remainder is 82 after subtracting 198 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 11:
When dividing 820 by 99, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 521.282828
If we take 792 away from 820, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
The number 99 fits into 280 2 times, leaving a remainder of 82.
Record the quotient 2 as the next digit in the result. 
Result so far: 521.2828282
The remainder is 82 after subtracting 198 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 13:
820 divided by 99 is 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 521.28282828
The remainder is 28 after subtracting 792 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 521.28282828 with a remainder of 2.8e-08.
