We look at the division of 70921 by 12 
Our goal is to divide 70921 by 12.

Advancing to step 1:
The number 12 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 12

Step 2:
If we divide 70 by 12, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 60 away from 70, we end up with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 12

Moving on to step 3:
The number 12 fits into 109 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 59.0
If we subtract 108 from 109, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 12

Going ahead to step 4:
The number 12 fits into 12 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 591.0
Subtract 12 from 12 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 12

Let's proceed to step 5:
12 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 5910.0
Subtract 0 from 1 to get 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 6:
The number 12 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 5910.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 5910.08
Subtracting 96 from 100 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.

Step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 5910.083
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.

Advancing to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 5910.0833
If we subtract 36 from 40, 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.

Our division results in 5910.0833 with a remaining 4e-05.
