378897 divided by 45 
Our goal is to divide 378897 by 45.

Going ahead to step 1:
45 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 45

Going ahead to step 2:
When dividing 37 by 45, we get 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 45

Moving on to step 3:
45 goes into 378 8 times with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 360 from 378 to get 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 45

Step 4:
If we divide 188 by 45, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 84.0
Deduct 180 from 188 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 45

Moving on to step 5:
When dividing 89 by 45, we get 1 with a remainder of 44.
The next digit of our result is 1. 
Result so far: 841.0
Deduct 45 from 89 and we're left with 44.
Append the next digit (7) from the dividend to 44 and continue with: 447 / 45

Advancing to step 6:
The number 45 fits into 447 9 times, leaving a remainder of 42.
The next digit of our result is 9. 
Result so far: 8419.0
The remainder is 42 after subtracting 405 from 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
When dividing 420 by 45, we get 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 8419.9
If we take 405 away from 420, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 8419.93
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 45 is 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 8419.933
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 8419.933, and the remainder is 0.0015.
