Let's divide 31518970 by 457
We want to figure out the number of times 31518970 can be divided by 457.

Step 1:
If we divide 3 by 457, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 457

On to step 2:
457 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 457

Step 3:
The number 457 fits into 315 0 times, leaving a remainder of 315.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 315 to get 315.
Bring next digit (1) of the dividend behind the 315 and repeat the process: 3151 / 457

On to step 4:
457 can be fit into 3151 6 times, resulting in a remainder of 409.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 2742 from 3151 leaves us with 409.
Append the next digit (8) from the dividend to 409 and continue with: 4098 / 457

Going ahead to step 5:
If we divide 4098 by 457, we get 8 and a remainder of 442.
The next digit of our result is 8. 
Result so far: 68.0
If we take 3656 away from 4098, we end up with 442.
Append the next digit (9) from the dividend to 442 and continue with: 4429 / 457

Let's proceed to step 6:
When dividing 4429 by 457, we get 9 with a remainder of 316.
Put 9 as the next digit of the answer. 
Result so far: 689.0
If we subtract 4113 from 4429, we get 316.
Append the next digit (7) from the dividend to 316 and continue with: 3167 / 457

Advancing to step 7:
457 goes into 3167 6 times with a remainder of 425.
The next digit of our result is 6. 
Result so far: 6896.0
Deduct 2742 from 3167 and we're left with 425.
Bring next digit (0) of the dividend behind the 425 and repeat the process: 4250 / 457

Going ahead to step 8:
When dividing 4250 by 457, we get 9 with a remainder of 137.
Use 9 as the next digit of our solution. 
Result so far: 68969.0
Subtracting 4113 from 4250 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 9:
1370 divided by 457 is 2 with a remainder of 456.
Record the quotient 2 as the next digit in the result. 
Result so far: 68969.2
The remainder is 456 after subtracting 914 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 10:
The number 457 fits into 4560 9 times, leaving a remainder of 447.
Put 9 as the next digit of the answer. 
Result so far: 68969.29
Deduct 4113 from 4560 and we're left with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Advancing to step 11:
457 goes into 4470 9 times with a remainder of 357.
Record the quotient 9 as the next digit in the result. 
Result so far: 68969.299
Deduct 4113 from 4470 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

In conclusion, the division gives 68969.299 with a balance of 0.0357.
