90378020 divided by 877 
We want to figure out the number of times 90378020 can be divided by 877.

On to step 1:
When dividing 9 by 877, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 877

Going ahead to step 2:
If we divide 90 by 877, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Take the next digit (3) from the dividend and append it to 90, then repeat: 903 / 877

Step 3:
903 divided by 877 is 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 877 from 903, we get 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 877

Moving on to step 4:
When dividing 267 by 877, we get 0 with a remainder of 267.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 267 after subtracting 0 from 267.
Include the next digit (8) from the dividend after 267, then repeat: 2678 / 877

Going ahead to step 5:
877 goes into 2678 3 times with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
If we subtract 2631 from 2678, we get 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 877

Let's proceed to step 6:
If we divide 470 by 877, we get 0 and a remainder of 470.
Write down 0 as next digit of the result. 
Result so far: 1030.0
If we take 0 away from 470, we end up with 470.
Take the next digit (2) from the dividend and append it to 470, then repeat: 4702 / 877

Step 7:
If we divide 4702 by 877, we get 5 and a remainder of 317.
The number 5 becomes the next digit in our result. 
Result so far: 10305.0
If we subtract 4385 from 4702, we get 317.
Take the next digit (0) from the dividend and append it to 317, then repeat: 3170 / 877

Going ahead to step 8:
When dividing 3170 by 877, we get 3 with a remainder of 539.
Use 3 as the next digit of our solution. 
Result so far: 103053.0
Deduct 2631 from 3170 and we're left with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

On to step 9:
877 goes into 5390 6 times with a remainder of 128.
Record the quotient 6 as the next digit in the result. 
Result so far: 103053.6
Subtract 5262 from 5390 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 10:
The number 877 fits into 1280 1 times, leaving a remainder of 403.
Use 1 as the next digit of our solution. 
Result so far: 103053.61
If we take 877 away from 1280, we end up with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Going ahead to step 11:
When dividing 4030 by 877, we get 4 with a remainder of 522.
Record the quotient 4 as the next digit in the result. 
Result so far: 103053.614
If we take 3508 away from 4030, we end up with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 12:
The number 877 fits into 5220 5 times, leaving a remainder of 835.
Write down 5 as next digit of the result. 
Result so far: 103053.6145
The remainder is 835 after subtracting 4385 from 5220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Let's proceed to step 13:
The number 877 fits into 8350 9 times, leaving a remainder of 457.
Use 9 as the next digit of our solution. 
Result so far: 103053.61459
Subtracting 7893 from 8350 leaves us with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Let's proceed to step 14:
877 goes into 4570 5 times with a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 103053.614595
If we take 4385 away from 4570, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 15:
1850 divided by 877 is 2 with a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 103053.6145952
Subtract 1754 from 1850 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 16:
877 goes into 960 1 times with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 103053.61459521
If we take 877 away from 960, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The final outcome is 103053.61459521, with a leftover of 8.3e-08.
