We look at the division of 70636405 by 979 
We want to divide 70636405 by 979.

On to step 1:
7 divided by 979 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 979

On to step 2:
70 divided by 979 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Fetch the next digit (6) from the dividend, attach it to 70 and continue: 706 / 979

Moving on to step 3:
If we divide 706 by 979, we get 0 and a remainder of 706.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 706 after subtracting 0 from 706.
Include the next digit (3) from the dividend after 706, then repeat: 7063 / 979

Moving on to step 4:
When dividing 7063 by 979, we get 7 with a remainder of 210.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 6853 from 7063 and we're left with 210.
Include the next digit (6) from the dividend after 210, then repeat: 2106 / 979

Going ahead to step 5:
When dividing 2106 by 979, we get 2 with a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 72.0
The remainder is 148 after subtracting 1958 from 2106.
Fetch the next digit (4) from the dividend, attach it to 148 and continue: 1484 / 979

Let's proceed to step 6:
979 goes into 1484 1 times with a remainder of 505.
The next digit of our result is 1. 
Result so far: 721.0
The remainder is 505 after subtracting 979 from 1484.
Take the next digit (0) from the dividend and append it to 505, then repeat: 5050 / 979

Let's proceed to step 7:
5050 divided by 979 is 5 with a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 7215.0
Subtract 4895 from 5050 to get 155.
Grab the next digit (5) from the dividend, add it to 155, then carry on: 1555 / 979

On to step 8:
The number 979 fits into 1555 1 times, leaving a remainder of 576.
Put 1 as the next digit of the answer. 
Result so far: 72151.0
If we take 979 away from 1555, we end up with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Step 9:
979 can be fit into 5760 5 times, resulting in a remainder of 865.
Use 5 as the next digit of our solution. 
Result so far: 72151.5
The remainder is 865 after subtracting 4895 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

Let's proceed to step 10:
When dividing 8650 by 979, we get 8 with a remainder of 818.
The number 8 becomes the next digit in our result. 
Result so far: 72151.58
If we take 7832 away from 8650, we end up with 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

On to step 11:
979 can be fit into 8180 8 times, resulting in a remainder of 348.
Write down 8 as next digit of the result. 
Result so far: 72151.588
If we subtract 7832 from 8180, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

The final result is 72151.588 with a remainder of 0.0348.
