We look at the division of 122358 by 43 
We want to figure out the number of times 122358 can be divided by 43.

Let's proceed to step 1:
When dividing 1 by 43, we get 0 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.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 43

Going ahead to step 2:
When dividing 12 by 43, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 43

Advancing to step 3:
43 goes into 122 2 times with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 86 from 122 to get 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 43

Going ahead to step 4:
43 goes into 363 8 times with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 19 after subtracting 344 from 363.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 43

Moving on to step 5:
43 goes into 195 4 times with a remainder of 23.
The next digit of our result is 4. 
Result so far: 284.0
If we take 172 away from 195, we end up with 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 43

On to step 6:
If we divide 238 by 43, we get 5 and a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 2845.0
Subtract 215 from 238 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
230 divided by 43 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 2845.5
Subtracting 215 from 230 leaves us 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 8:
150 divided by 43 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 2845.53
If we take 129 away from 150, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
When dividing 210 by 43, we get 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 2845.534
Deduct 172 from 210 and we're left 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.

Going ahead to step 10:
The number 43 fits into 380 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 2845.5348
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
If we divide 360 by 43, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 2845.53488
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 2845.53488 with a remaining 1.6e-05.
