We divide 87427 by 51
We want to figure out the number of times 87427 can be divided by 51.

On to step 1:
If we divide 8 by 51, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 51

Step 2:
When dividing 87 by 51, we get 1 with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 51 from 87 to get 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 51

On to step 3:
51 goes into 364 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 357 from 364 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 51

Moving on to step 4:
The number 51 fits into 72 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
If we subtract 51 from 72, we get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 51

Advancing to step 5:
If we divide 217 by 51, we get 4 and a remainder of 13.
The next digit of our result is 4. 
Result so far: 1714.0
Deduct 204 from 217 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 6:
51 goes into 130 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 1714.2
Deduct 102 from 130 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
If we divide 280 by 51, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1714.25
Subtracting 255 from 280 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
If we divide 250 by 51, we get 4 and a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 1714.254
Deduct 204 from 250 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
If we divide 460 by 51, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1714.2549
Subtracting 459 from 460 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
If we divide 10 by 51, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1714.2549
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
The number 51 fits into 100 1 times, leaving a remainder of 49.
The next digit of our result is 1. 
Result so far: 1714.254901
Subtract 51 from 100 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 12:
The number 51 fits into 490 9 times, leaving a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 1714.2549019
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 13:
The number 51 fits into 310 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1714.25490196
If we subtract 306 from 310, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 1714.25490196, and the remainder is 4e-09.
