121930 ÷ 43 
We're looking to find how many times 43 goes into 121930.

Moving on to step 1:
1 divided by 43 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 43

Moving on to step 2:
12 divided by 43 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 43

Moving on to step 3:
The number 43 fits into 121 2 times, leaving a remainder of 35.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 35 after subtracting 86 from 121.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 43

Let's proceed to step 4:
If we divide 359 by 43, we get 8 and a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 15 after subtracting 344 from 359.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 43

Advancing to step 5:
The number 43 fits into 153 3 times, leaving a remainder of 24.
The next digit of our result is 3. 
Result so far: 283.0
If we subtract 129 from 153, we get 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 43

Moving on to step 6:
240 divided by 43 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 2835.0
If we take 215 away from 240, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
When dividing 250 by 43, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2835.5
The remainder is 35 after subtracting 215 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
43 goes into 350 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 2835.58
Subtract 344 from 350 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
60 divided by 43 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 2835.581
The remainder is 17 after subtracting 43 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
43 can be fit into 170 3 times, resulting in a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 2835.5813
Deduct 129 from 170 and we're left with 41.
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 11:
If we divide 410 by 43, we get 9 and a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 2835.58139
If we subtract 387 from 410, we 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.

On to step 12:
43 can be fit into 230 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 2835.581395
Subtract 215 from 230 to get 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 13:
The number 43 fits into 150 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 2835.5813953
Deduct 129 from 150 and we're left 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.

Advancing to step 14:
210 divided by 43 is 4 with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 2835.58139534
Subtract 172 from 210 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 2835.58139534 and a remainder of 3.8e-08.
