We divide 99658661 by 51
We want to figure out the number of times 99658661 can be divided by 51.

Let's proceed to step 1:
9 divided by 51 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 51

On to step 2:
51 can be fit into 99 1 times, resulting in a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 51 from 99 leaves us with 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 51

Moving on to step 3:
51 goes into 486 9 times with a remainder of 27.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 459 from 486 leaves us with 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 51

Moving on to step 4:
51 goes into 275 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 195.0
Deduct 255 from 275 and we're left with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 51

Let's proceed to step 5:
When dividing 208 by 51, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 1954.0
The remainder is 4 after subtracting 204 from 208.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 51

Moving on to step 6:
The number 51 fits into 46 0 times, leaving a remainder of 46.
Record the quotient 0 as the next digit in the result. 
Result so far: 19540.0
Subtract 0 from 46 to get 46.
Append the next digit (6) from the dividend to 46 and continue with: 466 / 51

Advancing to step 7:
51 can be fit into 466 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 195409.0
The remainder is 7 after subtracting 459 from 466.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 51

Moving on to step 8:
71 divided by 51 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1954091.0
The remainder is 20 after subtracting 51 from 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
51 goes into 200 3 times with a remainder of 47.
The next digit of our result is 3. 
Result so far: 1954091.3
The remainder is 47 after subtracting 153 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 10:
If we divide 470 by 51, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 1954091.39
Deduct 459 from 470 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
If we divide 110 by 51, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1954091.392
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
51 can be fit into 80 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1954091.3921
Subtracting 51 from 80 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
When dividing 290 by 51, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1954091.39215
If we subtract 255 from 290, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
When dividing 350 by 51, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 1954091.392156
The remainder is 44 after subtracting 306 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 15:
51 can be fit into 440 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 1954091.3921568
Subtracting 408 from 440 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 16:
51 goes into 320 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 1954091.39215686
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 1954091.39215686 with a remainder of 1.4e-08.
