Let's divide 870990 by 14
We want to figure out the number of times 870990 can be divided by 14.

Let's proceed to step 1:
The number 14 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 14

Step 2:
If we divide 87 by 14, we get 6 and a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 3 after subtracting 84 from 87.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 14

Let's proceed to step 3:
If we divide 30 by 14, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Subtract 28 from 30 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 14

Let's proceed to step 4:
29 divided by 14 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 622.0
Deduct 28 from 29 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 14

Let's proceed to step 5:
The number 14 fits into 19 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 6221.0
If we take 14 away from 19, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 14

On to step 6:
14 can be fit into 50 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 62213.0
If we subtract 42 from 50, we get 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 7:
The number 14 fits into 80 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 62213.5
If we subtract 70 from 80, we 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.

On to step 8:
If we divide 100 by 14, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 62213.57
Subtracting 98 from 100 leaves us 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 9:
20 divided by 14 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 62213.571
If we take 14 away from 20, we end up 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.

Let's proceed to step 10:
If we divide 60 by 14, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 62213.5714
Subtract 56 from 60 to 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.

Going ahead to step 11:
40 divided by 14 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 62213.57142
If we subtract 28 from 40, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
120 divided by 14 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 62213.571428
Deduct 112 from 120 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.

Let's proceed to step 13:
If we divide 80 by 14, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 62213.5714285
Subtracting 70 from 80 leaves us 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.

Advancing to step 14:
14 goes into 100 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 62213.57142857
Subtracting 98 from 100 leaves us 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.

After the division, we end up with 62213.57142857 and a remainder of 2e-09.
