We divide 90137803 by 9
We want to divide 90137803 by 9.

Step 1:
If we divide 9 by 9, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 9 from 9 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 9

Moving on to step 2:
When dividing 0 by 9, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 9

Going ahead to step 3:
9 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 100.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 9

Advancing to step 4:
When dividing 13 by 9, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1001.0
Deduct 9 from 13 and we're left with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 9

Moving on to step 5:
9 goes into 47 5 times with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 10015.0
If we subtract 45 from 47, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 9

Let's proceed to step 6:
If we divide 28 by 9, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 100153.0
If we take 27 away from 28, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 9

Let's proceed to step 7:
10 divided by 9 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1001531.0
If we take 9 away from 10, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 9

Let's proceed to step 8:
9 can be fit into 13 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 10015311.0
Deduct 9 from 13 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 9 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 10015311.4
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
When dividing 40 by 9, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 10015311.44
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 10015311.44 with a remaining 0.004.
