Let's divide 870672 by 70
We're looking to find how many times 70 goes into 870672.

Going ahead to step 1:
8 divided by 70 is 0 with 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 / 70

Advancing to step 2:
When dividing 87 by 70, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 70 from 87 and we're left with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 70

Advancing to step 3:
The number 70 fits into 170 2 times, leaving a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 140 from 170 leaves us with 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 70

Step 4:
70 can be fit into 306 4 times, resulting in a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Subtract 280 from 306 to get 26.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 70

On to step 5:
267 divided by 70 is 3 with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 1243.0
Subtract 210 from 267 to get 57.
Take the next digit (2) from the dividend and append it to 57, then repeat: 572 / 70

Going ahead to step 6:
70 goes into 572 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 12438.0
The remainder is 12 after subtracting 560 from 572.
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 7:
The number 70 fits into 120 1 times, leaving a remainder of 50.
The next digit of our result is 1. 
Result so far: 12438.1
Deduct 70 from 120 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.

Going ahead to step 8:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 12438.17
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.

Advancing to step 9:
If we divide 100 by 70, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 12438.171
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.

Going ahead to step 10:
70 goes into 300 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 12438.1714
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.

Step 11:
70 goes into 200 2 times with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 12438.17142
Subtracting 140 from 200 leaves us with 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:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 12438.171428
Deduct 560 from 600 and we're left 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.

Step 13:
70 goes into 400 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 12438.1714285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
70 can be fit into 500 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 12438.17142857
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 quotient of the division is 12438.17142857, and the remainder is 1e-08.
