We look at the division of 88220393 by 45 
Let's see how many times 45 fits into 88220393.

On to step 1:
45 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 45

Going ahead to step 2:
45 goes into 88 1 times with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 45 away from 88, we end up with 43.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 45

Let's proceed to step 3:
The number 45 fits into 432 9 times, leaving a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 405 from 432 and we're left with 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 45

Step 4:
If we divide 272 by 45, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 196.0
If we take 270 away from 272, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 45

Let's proceed to step 5:
If we divide 20 by 45, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1960.0
If we take 0 away from 20, we end up with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 45

Moving on to step 6:
When dividing 203 by 45, we get 4 with a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 19604.0
If we take 180 away from 203, we end up with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 45

Advancing to step 7:
When dividing 239 by 45, we get 5 with a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 196045.0
If we take 225 away from 239, we end up with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 45

Advancing to step 8:
45 goes into 143 3 times with a remainder of 8.
The next digit of our result is 3. 
Result so far: 1960453.0
The remainder is 8 after subtracting 135 from 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
When dividing 80 by 45, we get 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1960453.1
Deduct 45 from 80 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
45 goes into 350 7 times with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 1960453.17
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
350 divided by 45 is 7 with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 1960453.177
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 1960453.177 with a remainder of 0.0035.
