Let's divide 170880 by 43
We want to figure out the number of times 170880 can be divided by 43.

Going ahead to step 1:
43 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 43

Advancing to step 2:
The number 43 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 43

On to step 3:
When dividing 170 by 43, we get 3 with a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 129 away from 170, we end up with 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 43

Advancing to step 4:
418 divided by 43 is 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 387 away from 418, we end up with 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 43

Step 5:
318 divided by 43 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 397.0
If we take 301 away from 318, we end up with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 43

Moving on to step 6:
The number 43 fits into 170 3 times, leaving a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 3973.0
The remainder is 41 after subtracting 129 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
If we divide 410 by 43, we get 9 and a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 3973.9
The remainder is 23 after subtracting 387 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 8:
43 can be fit into 230 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 3973.95
Deduct 215 from 230 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 43 is 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 3973.953
The remainder is 21 after subtracting 129 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
210 divided by 43 is 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 3973.9534
If we take 172 away from 210, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
The number 43 fits into 380 8 times, leaving a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 3973.95348
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
43 goes into 360 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3973.953488
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 3973.953488, with a leftover of 1.6e-06.
