We look at the division of 90042773 by 878 
We want to figure out the number of times 90042773 can be divided by 878.

Advancing to step 1:
878 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 878

Advancing to step 2:
The number 878 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Include the next digit (0) from the dividend after 90, then repeat: 900 / 878

Step 3:
878 can be fit into 900 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
If we take 878 away from 900, we end up with 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 878

Advancing to step 4:
224 divided by 878 is 0 with a remainder of 224.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 224 after subtracting 0 from 224.
Fetch the next digit (2) from the dividend, attach it to 224 and continue: 2242 / 878

Going ahead to step 5:
878 goes into 2242 2 times with a remainder of 486.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Subtract 1756 from 2242 to get 486.
Take the next digit (7) from the dividend and append it to 486, then repeat: 4867 / 878

Going ahead to step 6:
878 can be fit into 4867 5 times, resulting in a remainder of 477.
Use 5 as the next digit of our solution. 
Result so far: 1025.0
If we take 4390 away from 4867, we end up with 477.
Take the next digit (7) from the dividend and append it to 477, then repeat: 4777 / 878

Step 7:
4777 divided by 878 is 5 with a remainder of 387.
Put 5 as the next digit of the answer. 
Result so far: 10255.0
If we take 4390 away from 4777, we end up with 387.
Grab the next digit (3) from the dividend, add it to 387, then carry on: 3873 / 878

On to step 8:
878 can be fit into 3873 4 times, resulting in a remainder of 361.
Record the quotient 4 as the next digit in the result. 
Result so far: 102554.0
Subtract 3512 from 3873 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Let's proceed to step 9:
3610 divided by 878 is 4 with a remainder of 98.
The number 4 becomes the next digit in our result. 
Result so far: 102554.4
Subtract 3512 from 3610 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 10:
878 goes into 980 1 times with a remainder of 102.
The number 1 becomes the next digit in our result. 
Result so far: 102554.41
The remainder is 102 after subtracting 878 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 11:
If we divide 1020 by 878, we get 1 and a remainder of 142.
Put 1 as the next digit of the answer. 
Result so far: 102554.411
The remainder is 142 after subtracting 878 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The quotient of the division is 102554.411, and the remainder is 0.0142.
