151863 ÷ 10 
We want to figure out the number of times 151863 can be divided by 10.

Step 1:
1 divided by 10 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 10

Moving on to step 2:
15 divided by 10 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 10 away from 15, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 10

Moving on to step 3:
10 can be fit into 51 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 50 from 51 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 10

Step 4:
The number 10 fits into 18 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 151.0
Deduct 10 from 18 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 10

Advancing to step 5:
When dividing 86 by 10, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 1518.0
Deduct 80 from 86 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 10

On to step 6:
If we divide 63 by 10, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 15186.0
Deduct 60 from 63 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 10 fits into 30 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 15186.3
If we subtract 30 from 30, 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 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15186.3
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.

Going ahead to step 9:
0 divided by 10 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15186.3
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 quotient of the division is 15186.3, and the remainder is 0.0.
