Let's divide 7856660 by 45
We want to divide 7856660 by 45.

Advancing to step 1:
7 divided by 45 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 45

Moving on to step 2:
78 divided by 45 is 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 45 away from 78, we end up with 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 45

Advancing to step 3:
When dividing 335 by 45, we get 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 315 from 335 leaves us with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 45

Advancing to step 4:
If we divide 206 by 45, we get 4 and a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 174.0
Deduct 180 from 206 and we're left with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 45

Going ahead to step 5:
When dividing 266 by 45, we get 5 with a remainder of 41.
Write down 5 as next digit of the result. 
Result so far: 1745.0
Subtract 225 from 266 to get 41.
Include the next digit (6) from the dividend after 41, then repeat: 416 / 45

Moving on to step 6:
If we divide 416 by 45, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 17459.0
Deduct 405 from 416 and we're left with 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 45

Moving on to step 7:
If we divide 110 by 45, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 174592.0
If we take 90 away from 110, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
45 goes into 200 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 174592.4
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
If we divide 200 by 45, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 174592.44
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 174592.44 with a remaining 0.02.
