Let's divide 12140688 by 170
We're looking to find how many times 170 goes into 12140688.

Step 1:
170 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 170

Going ahead to step 2:
170 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 170

Let's proceed to step 3:
The number 170 fits into 121 0 times, leaving a remainder of 121.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 121 to get 121.
Grab the next digit (4) from the dividend, add it to 121, then carry on: 1214 / 170

Step 4:
170 can be fit into 1214 7 times, resulting in a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 1190 from 1214 and we're left with 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 170

Moving on to step 5:
240 divided by 170 is 1 with a remainder of 70.
The next digit of our result is 1. 
Result so far: 71.0
If we subtract 170 from 240, we get 70.
Grab the next digit (6) from the dividend, add it to 70, then carry on: 706 / 170

Let's proceed to step 6:
706 divided by 170 is 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 714.0
If we subtract 680 from 706, we get 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 170

On to step 7:
When dividing 268 by 170, we get 1 with a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 7141.0
If we take 170 away from 268, we end up with 98.
Include the next digit (8) from the dividend after 98, then repeat: 988 / 170

Going ahead to step 8:
The number 170 fits into 988 5 times, leaving a remainder of 138.
The next digit of our result is 5. 
Result so far: 71415.0
If we take 850 away from 988, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 9:
When dividing 1380 by 170, we get 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 71415.8
If we subtract 1360 from 1380, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
200 divided by 170 is 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 71415.81
If we subtract 170 from 200, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
The number 170 fits into 300 1 times, leaving a remainder of 130.
The number 1 becomes the next digit in our result. 
Result so far: 71415.811
The remainder is 130 after subtracting 170 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

In conclusion, the division gives 71415.811 with a balance of 0.013.
