811392 ÷ 70 
Our goal is to divide 811392 by 70.

Step 1:
8 divided by 70 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 70

Moving on to step 2:
If we divide 81 by 70, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 11 after subtracting 70 from 81.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 70

Advancing to step 3:
If we divide 111 by 70, we get 1 and a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 70 from 111 and we're left with 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 70

On to step 4:
413 divided by 70 is 5 with a remainder of 63.
Use 5 as the next digit of our solution. 
Result so far: 115.0
Subtracting 350 from 413 leaves us with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 70

Moving on to step 5:
The number 70 fits into 639 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 1159.0
Deduct 630 from 639 and we're left with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 70

Moving on to step 6:
The number 70 fits into 92 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 11591.0
Subtracting 70 from 92 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
The number 70 fits into 220 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 11591.3
If we take 210 away from 220, we end up 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.

Step 8:
If we divide 100 by 70, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 11591.31
Subtracting 70 from 100 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
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: 11591.314
Subtracting 280 from 300 leaves us 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 10:
70 goes into 200 2 times with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 11591.3142
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.

Step 11:
When dividing 600 by 70, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 11591.31428
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.

Advancing to step 12:
70 goes into 400 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 11591.314285
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.

Going ahead to step 13:
70 goes into 500 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 11591.3142857
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.

Step 14:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 11591.31428571
If we take 70 away from 100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 11591.31428571 with a remainder of 3e-08.
