Let's divide 901022 by 12
We want to figure out the number of times 901022 can be divided by 12.

Advancing to step 1:
The number 12 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 12

Step 2:
90 divided by 12 is 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 84 from 90, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 12

Let's proceed to step 3:
61 divided by 12 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtract 60 from 61 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 12

Let's proceed to step 4:
The number 12 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 750.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 12

Step 5:
When dividing 102 by 12, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 7508.0
Deduct 96 from 102 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 12

On to step 6:
62 divided by 12 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 75085.0
If we take 60 away from 62, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
12 can be fit into 20 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 75085.1
The remainder is 8 after subtracting 12 from 20.
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 8:
If we divide 80 by 12, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 75085.16
Subtracting 72 from 80 leaves us with 8.
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 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 75085.166
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 75085.166, with a leftover of 0.0008.
