We look at the division of 31200155 by 722 
Let's see how many times 722 fits into 31200155.

Advancing to step 1:
The number 722 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 722

Let's proceed to step 2:
31 divided by 722 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 722

Going ahead to step 3:
The number 722 fits into 312 0 times, leaving a remainder of 312.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 312, we get 312.
Fetch the next digit (0) from the dividend, attach it to 312 and continue: 3120 / 722

Let's proceed to step 4:
The number 722 fits into 3120 4 times, leaving a remainder of 232.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 2888 away from 3120, we end up with 232.
Fetch the next digit (0) from the dividend, attach it to 232 and continue: 2320 / 722

Going ahead to step 5:
2320 divided by 722 is 3 with a remainder of 154.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we take 2166 away from 2320, we end up with 154.
Bring next digit (1) of the dividend behind the 154 and repeat the process: 1541 / 722

Moving on to step 6:
1541 divided by 722 is 2 with a remainder of 97.
The number 2 becomes the next digit in our result. 
Result so far: 432.0
Subtracting 1444 from 1541 leaves us with 97.
Grab the next digit (5) from the dividend, add it to 97, then carry on: 975 / 722

Moving on to step 7:
The number 722 fits into 975 1 times, leaving a remainder of 253.
The next digit of our result is 1. 
Result so far: 4321.0
Subtract 722 from 975 to get 253.
Fetch the next digit (5) from the dividend, attach it to 253 and continue: 2535 / 722

Step 8:
2535 divided by 722 is 3 with a remainder of 369.
The number 3 becomes the next digit in our result. 
Result so far: 43213.0
Subtracting 2166 from 2535 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Let's proceed to step 9:
If we divide 3690 by 722, we get 5 and a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 43213.5
If we take 3610 away from 3690, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
800 divided by 722 is 1 with a remainder of 78.
Put 1 as the next digit of the answer. 
Result so far: 43213.51
The remainder is 78 after subtracting 722 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 11:
When dividing 780 by 722, we get 1 with a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 43213.511
Subtracting 722 from 780 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 43213.511, and the remainder is 0.0058.
