We're dividing 812638 by 70 
Let's see how many times 70 fits into 812638.

Let's proceed to step 1:
70 goes into 8 0 times 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.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 70

Going ahead to step 2:
70 goes into 81 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 70 from 81 to get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 70

On to step 3:
112 divided by 70 is 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 70 from 112 to get 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 70

Moving on to step 4:
The number 70 fits into 426 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
If we take 420 away from 426, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 70

On to step 5:
When dividing 63 by 70, we get 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 1160.0
If we subtract 0 from 63, we get 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 70

Step 6:
The number 70 fits into 638 9 times, leaving a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 11609.0
The remainder is 8 after subtracting 630 from 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
The number 70 fits into 80 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 11609.1
If we take 70 away from 80, 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.

On to step 8:
When dividing 100 by 70, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 11609.11
Deduct 70 from 100 and we're left 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.

After the division, we end up with 11609.11 and a remainder of 0.03.
