712121 divided by 9 
Our goal is to divide 712121 by 9.

Step 1:
9 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 9

Advancing to step 2:
When dividing 71 by 9, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 8 after subtracting 63 from 71.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 9

Advancing to step 3:
The number 9 fits into 82 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Subtract 81 from 82 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 9

Step 4:
11 divided by 9 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 791.0
Deduct 9 from 11 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 9

Let's proceed to step 5:
If we divide 22 by 9, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 7912.0
Subtract 18 from 22 to get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 9

Moving on to step 6:
41 divided by 9 is 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 79124.0
Subtract 36 from 41 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
If we divide 50 by 9, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 79124.5
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
When dividing 50 by 9, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 79124.55
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 79124.55, and the remainder is 0.005.
