We're dividing 90357031 by 13 
Our goal is to divide 90357031 by 13.

On to step 1:
If we divide 9 by 13, we get 0 and 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.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 13

Let's proceed to step 2:
13 goes into 90 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 78 from 90 and we're left with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 13

Moving on to step 3:
When dividing 123 by 13, we get 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 69.0
Deduct 117 from 123 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 13

On to step 4:
When dividing 65 by 13, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 695.0
Subtract 65 from 65 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 13

Moving on to step 5:
When dividing 7 by 13, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 6950.0
Subtract 0 from 7 to get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 13

On to step 6:
13 goes into 70 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 69505.0
Subtract 65 from 70 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 13

On to step 7:
If we divide 53 by 13, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 695054.0
If we take 52 away from 53, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 13

Advancing to step 8:
If we divide 11 by 13, we get 0 and a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 6950540.0
Subtracting 0 from 11 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
If we divide 110 by 13, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 6950540.8
Subtracting 104 from 110 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 6950540.84
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
80 divided by 13 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 6950540.846
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
13 goes into 20 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 6950540.8461
Subtracting 13 from 20 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
The number 13 fits into 70 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 6950540.84615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
When dividing 50 by 13, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 6950540.846153
If we subtract 39 from 50, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 15:
13 goes into 110 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 6950540.8461538
Deduct 104 from 110 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 16:
If we divide 60 by 13, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 6950540.84615384
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 6950540.84615384 and a remainder of 8e-09.
