31230810 divided by 731 
We want to divide 31230810 by 731.

On to step 1:
When dividing 3 by 731, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 731

Moving on to step 2:
The number 731 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 731

Step 3:
The number 731 fits into 312 0 times, leaving a remainder of 312.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 312, we end up with 312.
Include the next digit (3) from the dividend after 312, then repeat: 3123 / 731

On to step 4:
The number 731 fits into 3123 4 times, leaving a remainder of 199.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 2924 from 3123 and we're left with 199.
Append the next digit (0) from the dividend to 199 and continue with: 1990 / 731

Moving on to step 5:
731 can be fit into 1990 2 times, resulting in a remainder of 528.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtract 1462 from 1990 to get 528.
Append the next digit (8) from the dividend to 528 and continue with: 5288 / 731

Step 6:
5288 divided by 731 is 7 with a remainder of 171.
The next digit of our result is 7. 
Result so far: 427.0
If we take 5117 away from 5288, we end up with 171.
Include the next digit (1) from the dividend after 171, then repeat: 1711 / 731

Let's proceed to step 7:
731 goes into 1711 2 times with a remainder of 249.
Write down 2 as next digit of the result. 
Result so far: 4272.0
The remainder is 249 after subtracting 1462 from 1711.
Append the next digit (0) from the dividend to 249 and continue with: 2490 / 731

Let's proceed to step 8:
731 goes into 2490 3 times with a remainder of 297.
Put 3 as the next digit of the answer. 
Result so far: 42723.0
The remainder is 297 after subtracting 2193 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Let's proceed to step 9:
731 can be fit into 2970 4 times, resulting in a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 42723.4
If we take 2924 away from 2970, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
If we divide 460 by 731, we get 0 and a remainder of 460.
Write down 0 as next digit of the result. 
Result so far: 42723.4
Subtract 0 from 460 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 11:
731 goes into 4600 6 times with a remainder of 214.
Record the quotient 6 as the next digit in the result. 
Result so far: 42723.406
The remainder is 214 after subtracting 4386 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 12:
If we divide 2140 by 731, we get 2 and a remainder of 678.
Write down 2 as next digit of the result. 
Result so far: 42723.4062
If we take 1462 away from 2140, we end up with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Let's proceed to step 13:
6780 divided by 731 is 9 with a remainder of 201.
The number 9 becomes the next digit in our result. 
Result so far: 42723.40629
Deduct 6579 from 6780 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 14:
2010 divided by 731 is 2 with a remainder of 548.
The number 2 becomes the next digit in our result. 
Result so far: 42723.406292
If we take 1462 away from 2010, we end up with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 15:
When dividing 5480 by 731, we get 7 with a remainder of 363.
Use 7 as the next digit of our solution. 
Result so far: 42723.4062927
The remainder is 363 after subtracting 5117 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Going ahead to step 16:
731 can be fit into 3630 4 times, resulting in a remainder of 706.
Put 4 as the next digit of the answer. 
Result so far: 42723.40629274
If we take 2924 away from 3630, we end up with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

The quotient of the division is 42723.40629274, and the remainder is 7.06e-07.
