43949049 divided by 258 
We're looking to find how many times 258 goes into 43949049.

Advancing to step 1:
When dividing 4 by 258, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 258

On to step 2:
The number 258 fits into 43 0 times, leaving a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 258

Step 3:
The number 258 fits into 439 1 times, leaving a remainder of 181.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 181 after subtracting 258 from 439.
Take the next digit (4) from the dividend and append it to 181, then repeat: 1814 / 258

Advancing to step 4:
If we divide 1814 by 258, we get 7 and a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 1806 from 1814, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 258

On to step 5:
When dividing 89 by 258, we get 0 with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
The remainder is 89 after subtracting 0 from 89.
Fetch the next digit (0) from the dividend, attach it to 89 and continue: 890 / 258

Advancing to step 6:
If we divide 890 by 258, we get 3 and a remainder of 116.
The number 3 becomes the next digit in our result. 
Result so far: 1703.0
Subtract 774 from 890 to get 116.
Grab the next digit (4) from the dividend, add it to 116, then carry on: 1164 / 258

Moving on to step 7:
If we divide 1164 by 258, we get 4 and a remainder of 132.
The number 4 becomes the next digit in our result. 
Result so far: 17034.0
Subtract 1032 from 1164 to get 132.
Grab the next digit (9) from the dividend, add it to 132, then carry on: 1329 / 258

Going ahead to step 8:
1329 divided by 258 is 5 with a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 170345.0
Subtract 1290 from 1329 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
The number 258 fits into 390 1 times, leaving a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 170345.1
Subtract 258 from 390 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 10:
258 goes into 1320 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 170345.15
Subtracting 1290 from 1320 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
258 goes into 300 1 times with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 170345.151
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
When dividing 420 by 258, we get 1 with a remainder of 162.
The next digit of our result is 1. 
Result so far: 170345.1511
Subtracting 258 from 420 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

After the division, we end up with 170345.1511 and a remainder of 0.00162.
