We're dividing 91879060 by 12 
We're looking to find how many times 12 goes into 91879060.

Moving on to step 1:
9 divided by 12 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 12

Advancing to step 2:
12 goes into 91 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 84 from 91, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 12

Let's proceed to step 3:
When dividing 78 by 12, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtract 72 from 78 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 12

Step 4:
The number 12 fits into 67 5 times, leaving a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 765.0
If we take 60 away from 67, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 12

On to step 5:
12 can be fit into 79 6 times, resulting in a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 7656.0
The remainder is 7 after subtracting 72 from 79.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 12

Let's proceed to step 6:
12 can be fit into 70 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 76565.0
Deduct 60 from 70 and we're left with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 12

Moving on to step 7:
When dividing 106 by 12, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 765658.0
If we subtract 96 from 106, we get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 12

On to step 8:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 7656588.0
Subtract 96 from 100 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.

On to step 9:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 7656588.3
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:
If we divide 40 by 12, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 7656588.33
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 7656588.33, with a leftover of 0.004.
