We look at the division of 615899 by 51 
We want to figure out the number of times 615899 can be divided by 51.

Let's proceed to step 1:
When dividing 6 by 51, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 51

Moving on to step 2:
51 can be fit into 61 1 times, resulting in a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 51 from 61, we get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 51

Step 3:
When dividing 105 by 51, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 102 from 105 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 51

On to step 4:
If we divide 38 by 51, we get 0 and a remainder of 38.
The next digit of our result is 0. 
Result so far: 120.0
Subtracting 0 from 38 leaves us with 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 51

Advancing to step 5:
51 can be fit into 389 7 times, resulting in a remainder of 32.
The next digit of our result is 7. 
Result so far: 1207.0
If we take 357 away from 389, we end up with 32.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 51

On to step 6:
329 divided by 51 is 6 with a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 12076.0
Subtract 306 from 329 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
When dividing 230 by 51, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 12076.4
Deduct 204 from 230 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
51 can be fit into 260 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 12076.45
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
50 divided by 51 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 12076.45
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
If we divide 500 by 51, we get 9 and a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 12076.4509
If we take 459 away from 500, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 11:
51 goes into 410 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 12076.45098
If we subtract 408 from 410, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
If we divide 20 by 51, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 12076.45098
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
The number 51 fits into 200 3 times, leaving a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 12076.4509803
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 14:
When dividing 470 by 51, we get 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 12076.45098039
Subtracting 459 from 470 leaves us 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.

After the division, we end up with 12076.45098039 and a remainder of 1.1e-08.
