987710 divided by 51 
We want to figure out the number of times 987710 can be divided by 51.

Going ahead to step 1:
The number 51 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 51

Let's proceed to step 2:
The number 51 fits into 98 1 times, leaving a remainder of 47.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 47 after subtracting 51 from 98.
Include the next digit (7) from the dividend after 47, then repeat: 477 / 51

On to step 3:
If we divide 477 by 51, we get 9 and a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 18 after subtracting 459 from 477.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 51

Moving on to step 4:
51 goes into 187 3 times with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 193.0
If we take 153 away from 187, we end up with 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 51

On to step 5:
When dividing 341 by 51, we get 6 with a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 1936.0
If we take 306 away from 341, we end up with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 51

Step 6:
The number 51 fits into 350 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 19366.0
If we take 306 away from 350, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
51 can be fit into 440 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 19366.8
If we subtract 408 from 440, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
If we divide 320 by 51, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 19366.86
Subtracting 306 from 320 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
140 divided by 51 is 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 19366.862
Deduct 102 from 140 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
380 divided by 51 is 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 19366.8627
Subtracting 357 from 380 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
If we divide 230 by 51, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 19366.86274
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
260 divided by 51 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 19366.862745
If we take 255 away from 260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
If we divide 50 by 51, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 19366.862745
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
51 can be fit into 500 9 times, resulting in a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 19366.86274509
Subtracting 459 from 500 leaves us 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.

The final result is 19366.86274509 with a remainder of 4.1e-08.
