We look at the division of 31493590 by 749 
We want to figure out the number of times 31493590 can be divided by 749.

Step 1:
3 divided by 749 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 749

Going ahead to step 2:
If we divide 31 by 749, we get 0 and a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 749

Moving on to step 3:
314 divided by 749 is 0 with a remainder of 314.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 314 after subtracting 0 from 314.
Include the next digit (9) from the dividend after 314, then repeat: 3149 / 749

Step 4:
When dividing 3149 by 749, we get 4 with a remainder of 153.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 2996 away from 3149, we end up with 153.
Bring next digit (3) of the dividend behind the 153 and repeat the process: 1533 / 749

Going ahead to step 5:
749 goes into 1533 2 times with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 1498 from 1533 leaves us with 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 749

Advancing to step 6:
When dividing 355 by 749, we get 0 with a remainder of 355.
The next digit of our result is 0. 
Result so far: 420.0
Subtracting 0 from 355 leaves us with 355.
Grab the next digit (9) from the dividend, add it to 355, then carry on: 3559 / 749

Step 7:
749 goes into 3559 4 times with a remainder of 563.
The next digit of our result is 4. 
Result so far: 4204.0
The remainder is 563 after subtracting 2996 from 3559.
Include the next digit (0) from the dividend after 563, then repeat: 5630 / 749

Advancing to step 8:
When dividing 5630 by 749, we get 7 with a remainder of 387.
Record the quotient 7 as the next digit in the result. 
Result so far: 42047.0
Subtract 5243 from 5630 to get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Moving on to step 9:
3870 divided by 749 is 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 42047.5
Deduct 3745 from 3870 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 10:
The number 749 fits into 1250 1 times, leaving a remainder of 501.
Write down 1 as next digit of the result. 
Result so far: 42047.51
If we take 749 away from 1250, we end up with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Going ahead to step 11:
When dividing 5010 by 749, we get 6 with a remainder of 516.
Write down 6 as next digit of the result. 
Result so far: 42047.516
Subtracting 4494 from 5010 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 12:
5160 divided by 749 is 6 with a remainder of 666.
Put 6 as the next digit of the answer. 
Result so far: 42047.5166
The remainder is 666 after subtracting 4494 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

In conclusion, the division gives 42047.5166 with a balance of 0.00666.
