451370 divided by 31 
We want to figure out the number of times 451370 can be divided by 31.

Going ahead to step 1:
31 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 31

Let's proceed to step 2:
When dividing 45 by 31, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 31 from 45, we get 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 31

Advancing to step 3:
When dividing 141 by 31, we get 4 with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 124 from 141 and we're left with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 31

On to step 4:
31 goes into 173 5 times with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 145.0
Subtracting 155 from 173 leaves us with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 31

Going ahead to step 5:
If we divide 187 by 31, we get 6 and a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 1456.0
If we take 186 away from 187, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 31

On to step 6:
When dividing 10 by 31, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 14560.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 14560.3
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
70 divided by 31 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 14560.32
Subtracting 62 from 70 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
When dividing 80 by 31, we get 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 14560.322
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 14560.322 and a remainder of 0.0018.
