We look at the division of 979131 by 45 
We want to figure out the number of times 979131 can be divided by 45.

Advancing to step 1:
When dividing 9 by 45, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 45

On to step 2:
When dividing 97 by 45, we get 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 90 from 97 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 45

On to step 3:
45 goes into 79 1 times with a remainder of 34.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 45 from 79 leaves us with 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 45

Step 4:
When dividing 341 by 45, we get 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 217.0
If we subtract 315 from 341, we get 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 45

Going ahead to step 5:
When dividing 263 by 45, we get 5 with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 2175.0
If we subtract 225 from 263, we get 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 45

Moving on to step 6:
45 can be fit into 381 8 times, resulting in a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 21758.0
Deduct 360 from 381 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
210 divided by 45 is 4 with a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 21758.4
Deduct 180 from 210 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.

Advancing to step 8:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 21758.46
If we subtract 270 from 300, 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.

On to step 9:
45 goes into 300 6 times with a remainder of 30.
The next digit of our result is 6. 
Result so far: 21758.466
Subtract 270 from 300 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.

The final result is 21758.466 with a remainder of 0.003.
