We look at the division of 970870 by 45 
We want to figure out the number of times 970870 can be divided by 45.

On to step 1:
If we divide 9 by 45, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 45

Advancing to step 2:
97 divided by 45 is 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 90 away from 97, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 45

On to step 3:
45 goes into 70 1 times with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 45 from 70 leaves us with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 45

Step 4:
If we divide 258 by 45, we get 5 and a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
Deduct 225 from 258 and we're left with 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 45

Step 5:
45 can be fit into 337 7 times, resulting in a remainder of 22.
The next digit of our result is 7. 
Result so far: 2157.0
Subtracting 315 from 337 leaves us with 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 45

Let's proceed to step 6:
45 goes into 220 4 times with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 21574.0
Subtract 180 from 220 to get 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 7:
400 divided by 45 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 21574.8
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
45 goes into 400 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 21574.88
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 21574.88, and the remainder is 0.04.
