151139 ÷ 10 
We want to figure out the number of times 151139 can be divided by 10.

Advancing to step 1:
If we divide 1 by 10, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 10

Going ahead to step 2:
10 goes into 15 1 times with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 10 away from 15, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 10

Let's proceed to step 3:
When dividing 51 by 10, we get 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 50 from 51, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 10

Moving on to step 4:
The number 10 fits into 11 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 151.0
Subtracting 10 from 11 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 10

Advancing to step 5:
10 goes into 13 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1511.0
The remainder is 3 after subtracting 10 from 13.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 10

On to step 6:
39 divided by 10 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 15113.0
Subtracting 30 from 39 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
10 goes into 90 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 15113.9
If we subtract 90 from 90, 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.

Step 8:
10 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15113.9
Subtracting 0 from 0 leaves us 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.

Advancing to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15113.9
Subtract 0 from 0 to 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.

The final outcome is 15113.9, with a leftover of 0.0.
