We look at the division of 157345 by 12 
Let's see how many times 12 fits into 157345.

Let's proceed to step 1:
12 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 12

Step 2:
The number 12 fits into 15 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 12 from 15, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 12

Advancing to step 3:
37 divided by 12 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 36 from 37 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 12

Step 4:
If we divide 13 by 12, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 131.0
Subtract 12 from 13 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 12

On to step 5:
12 goes into 14 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1311.0
Deduct 12 from 14 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 12

Advancing to step 6:
12 can be fit into 25 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 13112.0
Deduct 24 from 25 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 12 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 13112.0
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.

Moving on to step 8:
If we divide 100 by 12, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 13112.08
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 13112.083
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 13112.0833
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 13112.0833, and the remainder is 4e-05.
