Let's divide 90139185 by 108
We want to figure out the number of times 90139185 can be divided by 108.

Let's proceed to step 1:
The number 108 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 108

Moving on to step 2:
108 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Bring next digit (1) of the dividend behind the 90 and repeat the process: 901 / 108

Step 3:
108 can be fit into 901 8 times, resulting in a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 864 from 901 to get 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 108

Going ahead to step 4:
108 can be fit into 373 3 times, resulting in a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtracting 324 from 373 leaves us with 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 108

Moving on to step 5:
499 divided by 108 is 4 with a remainder of 67.
The number 4 becomes the next digit in our result. 
Result so far: 834.0
Subtracting 432 from 499 leaves us with 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 108

Going ahead to step 6:
108 can be fit into 671 6 times, resulting in a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 8346.0
Deduct 648 from 671 and we're left with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 108

Going ahead to step 7:
When dividing 238 by 108, we get 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 83462.0
If we subtract 216 from 238, we get 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 108

Let's proceed to step 8:
108 can be fit into 225 2 times, resulting in a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 834622.0
If we take 216 away from 225, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
108 can be fit into 90 0 times, resulting in a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 834622.0
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
The number 108 fits into 900 8 times, leaving a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 834622.08
If we subtract 864 from 900, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
108 goes into 360 3 times with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 834622.083
If we take 324 away from 360, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
The number 108 fits into 360 3 times, leaving a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 834622.0833
Deduct 324 from 360 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 834622.0833 with a remaining 0.00036.
