91354423 divided by 12 
We want to divide 91354423 by 12.

Moving on to step 1:
12 goes into 9 0 times with 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.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 12

Advancing to step 2:
If we divide 91 by 12, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 84 from 91 to get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 12

Let's proceed to step 3:
12 can be fit into 73 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Subtract 72 from 73 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 12

Step 4:
12 goes into 15 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 761.0
Subtracting 12 from 15 leaves us with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 12

On to step 5:
When dividing 34 by 12, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 7612.0
Subtract 24 from 34 to get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 12

Advancing to step 6:
The number 12 fits into 104 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 76128.0
If we subtract 96 from 104, we get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 12

Step 7:
The number 12 fits into 82 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 761286.0
Subtract 72 from 82 to get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 12

Going ahead to step 8:
The number 12 fits into 103 8 times, leaving a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 7612868.0
Subtract 96 from 103 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
70 divided by 12 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 7612868.5
If we subtract 60 from 70, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 7612868.58
The remainder is 4 after subtracting 96 from 100.
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:
If we divide 40 by 12, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 7612868.583
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 12:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 7612868.5833
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 7612868.5833 and a remainder of 4e-05.
