102157 ÷ 10 
We want to divide 102157 by 10.

Advancing to step 1:
10 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 10

Moving on to step 2:
The number 10 fits into 10 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we take 10 away from 10, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 10

On to step 3:
10 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 10

Advancing to step 4:
If we divide 21 by 10, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Deduct 20 from 21 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 10

Let's proceed to step 5:
10 can be fit into 15 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 1021.0
The remainder is 5 after subtracting 10 from 15.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 10

Let's proceed to step 6:
10 can be fit into 57 5 times, resulting in a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 10215.0
The remainder is 7 after subtracting 50 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
10 can be fit into 70 7 times, resulting in a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 10215.7
Subtract 70 from 70 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.

On to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10215.7
If we take 0 away from 0, we end up 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.

Moving on to step 9:
10 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10215.7
If we subtract 0 from 0, 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.

Our division results in 10215.7 with a remaining 0.0.
