We look at the division of 61878270 by 45 
We want to divide 61878270 by 45.

On to step 1:
6 divided by 45 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 45

Let's proceed to step 2:
If we divide 61 by 45, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 45 from 61 to get 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 45

Moving on to step 3:
45 can be fit into 168 3 times, resulting in a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 135 from 168 leaves us with 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 45

Going ahead to step 4:
The number 45 fits into 337 7 times, leaving a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Subtracting 315 from 337 leaves us with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 45

Let's proceed to step 5:
228 divided by 45 is 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 1375.0
Subtracting 225 from 228 leaves us with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 45

Advancing to step 6:
If we divide 32 by 45, we get 0 and a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 13750.0
If we subtract 0 from 32, we get 32.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 45

Let's proceed to step 7:
327 divided by 45 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 137507.0
Subtract 315 from 327 to get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 45

Advancing to step 8:
The number 45 fits into 120 2 times, leaving a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 1375072.0
If we subtract 90 from 120, 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.

Going ahead to step 9:
300 divided by 45 is 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 1375072.6
Subtracting 270 from 300 leaves us 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.

Moving on to step 10:
300 divided by 45 is 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 1375072.66
If we take 270 away from 300, we end up 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.

After the division, we end up with 1375072.66 and a remainder of 0.03.
