42991880 ÷ 230 
Let's see how many times 230 fits into 42991880.

Step 1:
When dividing 4 by 230, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 230

Let's proceed to step 2:
42 divided by 230 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 230

Going ahead to step 3:
If we divide 429 by 230, we get 1 and a remainder of 199.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 230 from 429 to get 199.
Take the next digit (9) from the dividend and append it to 199, then repeat: 1999 / 230

Advancing to step 4:
When dividing 1999 by 230, we get 8 with a remainder of 159.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 1840 from 1999, we get 159.
Append the next digit (1) from the dividend to 159 and continue with: 1591 / 230

Advancing to step 5:
230 goes into 1591 6 times with a remainder of 211.
Use 6 as the next digit of our solution. 
Result so far: 186.0
If we subtract 1380 from 1591, we get 211.
Append the next digit (8) from the dividend to 211 and continue with: 2118 / 230

On to step 6:
2118 divided by 230 is 9 with a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 1869.0
If we subtract 2070 from 2118, we get 48.
Append the next digit (8) from the dividend to 48 and continue with: 488 / 230

Let's proceed to step 7:
The number 230 fits into 488 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 18692.0
Deduct 460 from 488 and we're left with 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 230

Moving on to step 8:
When dividing 280 by 230, we get 1 with a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 186921.0
If we subtract 230 from 280, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
If we divide 500 by 230, we get 2 and a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 186921.2
The remainder is 40 after subtracting 460 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
The number 230 fits into 400 1 times, leaving a remainder of 170.
Record the quotient 1 as the next digit in the result. 
Result so far: 186921.21
Deduct 230 from 400 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 11:
230 can be fit into 1700 7 times, resulting in a remainder of 90.
Put 7 as the next digit of the answer. 
Result so far: 186921.217
Subtract 1610 from 1700 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
If we divide 900 by 230, we get 3 and a remainder of 210.
The next digit of our result is 3. 
Result so far: 186921.2173
Subtracting 690 from 900 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 13:
230 goes into 2100 9 times with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 186921.21739
If we subtract 2070 from 2100, 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.

Moving on to step 14:
If we divide 300 by 230, we get 1 and a remainder of 70.
The next digit of our result is 1. 
Result so far: 186921.217391
The remainder is 70 after subtracting 230 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 15:
The number 230 fits into 700 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 186921.2173913
Subtract 690 from 700 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 16:
The number 230 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 186921.2173913
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 186921.2173913 with a remainder of 1e-07.
