90879519 divided by 845 
We want to figure out the number of times 90879519 can be divided by 845.

Going ahead to step 1:
845 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 845

Going ahead to step 2:
The number 845 fits into 90 0 times, leaving a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Fetch the next digit (8) from the dividend, attach it to 90 and continue: 908 / 845

Moving on to step 3:
845 goes into 908 1 times with a remainder of 63.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 845 from 908 to get 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 845

Let's proceed to step 4:
845 goes into 637 0 times with a remainder of 637.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 637 after subtracting 0 from 637.
Include the next digit (9) from the dividend after 637, then repeat: 6379 / 845

Advancing to step 5:
The number 845 fits into 6379 7 times, leaving a remainder of 464.
Write down 7 as next digit of the result. 
Result so far: 107.0
Subtract 5915 from 6379 to get 464.
Take the next digit (5) from the dividend and append it to 464, then repeat: 4645 / 845

Moving on to step 6:
845 goes into 4645 5 times with a remainder of 420.
The number 5 becomes the next digit in our result. 
Result so far: 1075.0
If we subtract 4225 from 4645, we get 420.
Bring next digit (1) of the dividend behind the 420 and repeat the process: 4201 / 845

Let's proceed to step 7:
When dividing 4201 by 845, we get 4 with a remainder of 821.
Write down 4 as next digit of the result. 
Result so far: 10754.0
If we take 3380 away from 4201, we end up with 821.
Include the next digit (9) from the dividend after 821, then repeat: 8219 / 845

Moving on to step 8:
8219 divided by 845 is 9 with a remainder of 614.
Write down 9 as next digit of the result. 
Result so far: 107549.0
Deduct 7605 from 8219 and we're left with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Let's proceed to step 9:
The number 845 fits into 6140 7 times, leaving a remainder of 225.
Write down 7 as next digit of the result. 
Result so far: 107549.7
If we subtract 5915 from 6140, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 10:
845 can be fit into 2250 2 times, resulting in a remainder of 560.
The next digit of our result is 2. 
Result so far: 107549.72
If we subtract 1690 from 2250, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 11:
5600 divided by 845 is 6 with a remainder of 530.
Use 6 as the next digit of our solution. 
Result so far: 107549.726
The remainder is 530 after subtracting 5070 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 12:
845 can be fit into 5300 6 times, resulting in a remainder of 230.
Write down 6 as next digit of the result. 
Result so far: 107549.7266
If we take 5070 away from 5300, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The final result is 107549.7266 with a remainder of 0.0023.
