We divide 87455 by 51
We want to figure out the number of times 87455 can be divided by 51.

Step 1:
If we divide 8 by 51, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 51

Going ahead to step 2:
When dividing 87 by 51, we get 1 with a remainder of 36.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 51 from 87 leaves us with 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 51

Advancing to step 3:
364 divided by 51 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 357 from 364 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 51

Moving on to step 4:
The number 51 fits into 75 1 times, leaving a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
If we subtract 51 from 75, we get 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 51

Let's proceed to step 5:
51 goes into 245 4 times with a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 1714.0
Subtracting 204 from 245 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.

Advancing to step 6:
51 goes into 410 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 1714.8
If we take 408 away from 410, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
51 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1714.8
If we subtract 0 from 20, we 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.

Going ahead to step 8:
200 divided by 51 is 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 1714.803
Deduct 153 from 200 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
51 can be fit into 470 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1714.8039
Subtract 459 from 470 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
51 goes into 110 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 1714.80392
Deduct 102 from 110 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
If we divide 80 by 51, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1714.803921
Subtract 51 from 80 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 12:
51 can be fit into 290 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1714.8039215
Subtract 255 from 290 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 13:
51 can be fit into 350 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 1714.80392156
Deduct 306 from 350 and we're left 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.

Our division results in 1714.80392156 with a remaining 4.4e-08.
