981887 ÷ 51 
We want to divide 981887 by 51.

Step 1:
If we divide 9 by 51, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 51

Moving on to step 2:
98 divided by 51 is 1 with a remainder of 47.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 51 from 98 leaves us with 47.
Fetch the next digit (1) from the dividend, attach it to 47 and continue: 471 / 51

Advancing to step 3:
51 goes into 471 9 times with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 459 from 471 to get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 51

Step 4:
If we divide 128 by 51, we get 2 and a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 192.0
Deduct 102 from 128 and we're left with 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 51

On to step 5:
The number 51 fits into 268 5 times, leaving a remainder of 13.
The next digit of our result is 5. 
Result so far: 1925.0
If we subtract 255 from 268, we get 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 51

Step 6:
The number 51 fits into 137 2 times, leaving a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 19252.0
Subtract 102 from 137 to 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.

On to step 7:
51 can be fit into 350 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 19252.6
If we subtract 306 from 350, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
When dividing 440 by 51, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 19252.68
If we take 408 away from 440, we end up 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.

Going ahead to step 9:
51 goes into 320 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 19252.686
The remainder is 14 after subtracting 306 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
If we divide 140 by 51, we get 2 and a remainder of 38.
The next digit of our result is 2. 
Result so far: 19252.6862
Subtracting 102 from 140 leaves us 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.

Advancing to step 11:
If we divide 380 by 51, we get 7 and a remainder of 23.
The next digit of our result is 7. 
Result so far: 19252.68627
Deduct 357 from 380 and we're left 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.

Advancing to step 12:
51 goes into 230 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 19252.686274
Subtract 204 from 230 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 13:
The number 51 fits into 260 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 19252.6862745
Deduct 255 from 260 and we're left 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 14:
51 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 19252.6862745
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.

The final result is 19252.6862745 with a remainder of 5e-08.
