We divide 4025197 by 45
Our goal is to divide 4025197 by 45.

Step 1:
The number 45 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 45

Moving on to step 2:
When dividing 40 by 45, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 45

On to step 3:
45 can be fit into 402 8 times, resulting in a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 360 from 402 to get 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 45

Going ahead to step 4:
When dividing 425 by 45, we get 9 with a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 89.0
If we subtract 405 from 425, we get 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 45

Step 5:
45 goes into 201 4 times with a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 894.0
Deduct 180 from 201 and we're left with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 45

Moving on to step 6:
The number 45 fits into 219 4 times, leaving a remainder of 39.
The next digit of our result is 4. 
Result so far: 8944.0
Subtracting 180 from 219 leaves us with 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 45

Advancing to step 7:
If we divide 397 by 45, we get 8 and a remainder of 37.
The next digit of our result is 8. 
Result so far: 89448.0
The remainder is 37 after subtracting 360 from 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 8:
If we divide 370 by 45, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 89448.8
Subtracting 360 from 370 leaves us 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.

Going ahead to step 9:
45 goes into 100 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 89448.82
Subtracting 90 from 100 leaves us 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.

Moving on to step 10:
100 divided by 45 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 89448.822
If we take 90 away from 100, 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.

After the division, we end up with 89448.822 and a remainder of 0.001.
