We look at the division of 31393380 by 943 
We want to figure out the number of times 31393380 can be divided by 943.

On to step 1:
943 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 943

Step 2:
The number 943 fits into 31 0 times, leaving a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 943

Going ahead to step 3:
313 divided by 943 is 0 with a remainder of 313.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 313 leaves us with 313.
Bring next digit (9) of the dividend behind the 313 and repeat the process: 3139 / 943

Moving on to step 4:
If we divide 3139 by 943, we get 3 and a remainder of 310.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 2829 from 3139 leaves us with 310.
Include the next digit (3) from the dividend after 310, then repeat: 3103 / 943

Advancing to step 5:
If we divide 3103 by 943, we get 3 and a remainder of 274.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 2829 from 3103 and we're left with 274.
Append the next digit (3) from the dividend to 274 and continue with: 2743 / 943

Going ahead to step 6:
943 goes into 2743 2 times with a remainder of 857.
Write down 2 as next digit of the result. 
Result so far: 332.0
Deduct 1886 from 2743 and we're left with 857.
Take the next digit (8) from the dividend and append it to 857, then repeat: 8578 / 943

Step 7:
When dividing 8578 by 943, we get 9 with a remainder of 91.
Write down 9 as next digit of the result. 
Result so far: 3329.0
Subtracting 8487 from 8578 leaves us with 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 943

Advancing to step 8:
If we divide 910 by 943, we get 0 and a remainder of 910.
The number 0 becomes the next digit in our result. 
Result so far: 33290.0
Deduct 0 from 910 and we're left with 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

Going ahead to step 9:
The number 943 fits into 9100 9 times, leaving a remainder of 613.
The number 9 becomes the next digit in our result. 
Result so far: 33290.9
Subtract 8487 from 9100 to get 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Moving on to step 10:
The number 943 fits into 6130 6 times, leaving a remainder of 472.
Record the quotient 6 as the next digit in the result. 
Result so far: 33290.96
Subtract 5658 from 6130 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 11:
The number 943 fits into 4720 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 33290.965
If we subtract 4715 from 4720, we 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 12:
943 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 33290.965
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
943 can be fit into 500 0 times, resulting in a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 33290.965
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 33290.965 with a remainder of 0.0005.
