We're dividing 9212436 by 721 
Let's see how many times 721 fits into 9212436.

Going ahead to step 1:
The number 721 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 721

Let's proceed to step 2:
The number 721 fits into 92 0 times, leaving a remainder of 92.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 92 and we're left with 92.
Include the next digit (1) from the dividend after 92, then repeat: 921 / 721

Going ahead to step 3:
When dividing 921 by 721, we get 1 with a remainder of 200.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 721 away from 921, we end up with 200.
Take the next digit (2) from the dividend and append it to 200, then repeat: 2002 / 721

Moving on to step 4:
721 goes into 2002 2 times with a remainder of 560.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 1442 away from 2002, we end up with 560.
Take the next digit (4) from the dividend and append it to 560, then repeat: 5604 / 721

Moving on to step 5:
If we divide 5604 by 721, we get 7 and a remainder of 557.
Use 7 as the next digit of our solution. 
Result so far: 127.0
If we take 5047 away from 5604, we end up with 557.
Grab the next digit (3) from the dividend, add it to 557, then carry on: 5573 / 721

Let's proceed to step 6:
721 goes into 5573 7 times with a remainder of 526.
Put 7 as the next digit of the answer. 
Result so far: 1277.0
Subtract 5047 from 5573 to get 526.
Include the next digit (6) from the dividend after 526, then repeat: 5266 / 721

Step 7:
The number 721 fits into 5266 7 times, leaving a remainder of 219.
The next digit of our result is 7. 
Result so far: 12777.0
Deduct 5047 from 5266 and we're left with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Moving on to step 8:
2190 divided by 721 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 12777.3
If we subtract 2163 from 2190, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
When dividing 270 by 721, we get 0 with a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 12777.3
If we take 0 away from 270, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 10:
721 goes into 2700 3 times with a remainder of 537.
Put 3 as the next digit of the answer. 
Result so far: 12777.303
Subtracting 2163 from 2700 leaves us with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Going ahead to step 11:
The number 721 fits into 5370 7 times, leaving a remainder of 323.
The next digit of our result is 7. 
Result so far: 12777.3037
Subtract 5047 from 5370 to get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Moving on to step 12:
3230 divided by 721 is 4 with a remainder of 346.
Use 4 as the next digit of our solution. 
Result so far: 12777.30374
Deduct 2884 from 3230 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 13:
721 can be fit into 3460 4 times, resulting in a remainder of 576.
Record the quotient 4 as the next digit in the result. 
Result so far: 12777.303744
Deduct 2884 from 3460 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

In conclusion, the division gives 12777.303744 with a balance of 5.76e-05.
