31234570 ÷ 2 
Our goal is to divide 31234570 by 2.

Step 1:
If we divide 3 by 2, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 2 from 3 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Advancing to step 2:
2 can be fit into 11 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 10 from 11 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

On to step 3:
When dividing 12 by 2, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 156.0
The remainder is 0 after subtracting 12 from 12.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Moving on to step 4:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1561.0
If we take 2 away from 3, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

Advancing to step 5:
2 goes into 14 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 15617.0
The remainder is 0 after subtracting 14 from 14.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Advancing to step 6:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 156172.0
Subtracting 4 from 5 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 2

On to step 7:
When dividing 17 by 2, we get 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 1561728.0
Subtract 16 from 17 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

On to step 8:
10 divided by 2 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15617285.0
If we subtract 10 from 10, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15617285.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15617285.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 15617285.0, with a leftover of 0.0.
