We're dividing 51487 by 14 
Our goal is to divide 51487 by 14.

On to step 1:
14 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 14

Step 2:
14 can be fit into 51 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 42 from 51, we get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 14

Step 3:
The number 14 fits into 94 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
The remainder is 10 after subtracting 84 from 94.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 14

Advancing to step 4:
If we divide 108 by 14, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 367.0
The remainder is 10 after subtracting 98 from 108.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 14

Moving on to step 5:
The number 14 fits into 107 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 3677.0
If we take 98 away from 107, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 6:
14 goes into 90 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 3677.6
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
If we divide 60 by 14, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 3677.64
If we subtract 56 from 60, 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.

On to step 8:
When dividing 40 by 14, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 3677.642
Subtracting 28 from 40 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
14 can be fit into 120 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 3677.6428
Subtracting 112 from 120 leaves us 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.

Step 10:
When dividing 80 by 14, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3677.64285
Deduct 70 from 80 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
When dividing 100 by 14, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 3677.642857
Subtract 98 from 100 to 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.

Step 12:
If we divide 20 by 14, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 3677.6428571
Subtract 14 from 20 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
The number 14 fits into 60 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 3677.64285714
If we subtract 56 from 60, 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 3677.64285714, and the remainder is 4e-09.
