We're dividing 90338677 by 12 
We want to divide 90338677 by 12.

Advancing to step 1:
If we divide 9 by 12, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 12

Step 2:
The number 12 fits into 90 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 84 from 90 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 12

Going ahead to step 3:
12 can be fit into 63 5 times, resulting in a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtract 60 from 63 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 12

Let's proceed to step 4:
12 can be fit into 33 2 times, resulting in a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 752.0
Deduct 24 from 33 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 12

Let's proceed to step 5:
The number 12 fits into 98 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 7528.0
Deduct 96 from 98 and we're left with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 12

On to step 6:
The number 12 fits into 26 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 75282.0
If we subtract 24 from 26, we get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 12

Moving on to step 7:
If we divide 27 by 12, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 752822.0
Deduct 24 from 27 and we're left with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 12

Moving on to step 8:
12 goes into 37 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 7528223.0
Deduct 36 from 37 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
12 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 7528223.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
If we divide 100 by 12, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 7528223.08
If we subtract 96 from 100, 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.

On to step 11:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 7528223.083
Subtracting 36 from 40 leaves us 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.

Going ahead to step 12:
12 goes into 40 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 7528223.0833
Subtract 36 from 40 to 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.

The final outcome is 7528223.0833, with a leftover of 4e-05.
