We look at the division of 783879 by 70 
We want to divide 783879 by 70.

Going ahead to step 1:
70 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 70

Advancing to step 2:
78 divided by 70 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 70 from 78 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 70

Step 3:
The number 70 fits into 83 1 times, leaving a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 13 after subtracting 70 from 83.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 70

Let's proceed to step 4:
70 can be fit into 138 1 times, resulting in a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
Deduct 70 from 138 and we're left with 68.
Append the next digit (7) from the dividend to 68 and continue with: 687 / 70

Moving on to step 5:
When dividing 687 by 70, we get 9 with a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 1119.0
The remainder is 57 after subtracting 630 from 687.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 70

Going ahead to step 6:
The number 70 fits into 579 8 times, leaving a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 11198.0
Subtracting 560 from 579 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
If we divide 190 by 70, we get 2 and a remainder of 50.
The next digit of our result is 2. 
Result so far: 11198.2
If we subtract 140 from 190, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 11198.27
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
70 can be fit into 100 1 times, resulting in a remainder of 30.
The next digit of our result is 1. 
Result so far: 11198.271
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 11198.2714
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 11198.27142
Subtract 140 from 200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
When dividing 600 by 70, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 11198.271428
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
70 can be fit into 400 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 11198.2714285
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
When dividing 500 by 70, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 11198.27142857
Subtract 490 from 500 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.

The final outcome is 11198.27142857, with a leftover of 1e-08.
