We're dividing 76879 by 70 
We want to divide 76879 by 70.

Let's proceed to step 1:
When dividing 7 by 70, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 70

Going ahead to step 2:
70 goes into 76 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 70 from 76 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 70

Step 3:
70 goes into 68 0 times with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 68 and we're left with 68.
Bring next digit (7) of the dividend behind the 68 and repeat the process: 687 / 70

Going ahead to step 4:
687 divided by 70 is 9 with a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we take 630 away from 687, we end up with 57.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 70

Going ahead to step 5:
70 can be fit into 579 8 times, resulting in a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 1098.0
If we subtract 560 from 579, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 6:
If we divide 190 by 70, we get 2 and a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 1098.2
Deduct 140 from 190 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
If we divide 500 by 70, we get 7 and a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 1098.27
Deduct 490 from 500 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 8:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1098.271
If we subtract 70 from 100, we 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.

Advancing to step 9:
300 divided by 70 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 1098.2714
If we subtract 280 from 300, 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.

On to step 10:
70 goes into 200 2 times with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 1098.27142
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 11:
600 divided by 70 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 1098.271428
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
70 can be fit into 400 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 1098.2714285
If we take 350 away from 400, we end up with 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 13:
70 goes into 500 7 times with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 1098.27142857
Deduct 490 from 500 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.

The final outcome is 1098.27142857, with a leftover of 1e-08.
