We divide 148409 by 43
We want to figure out the number of times 148409 can be divided by 43.

On to step 1:
43 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 43

Going ahead to step 2:
43 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 43

On to step 3:
The number 43 fits into 148 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 3.0
If we take 129 away from 148, we end up with 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 43

Moving on to step 4:
43 can be fit into 194 4 times, resulting in a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we subtract 172 from 194, we get 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 43

Step 5:
220 divided by 43 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 345.0
If we take 215 away from 220, we end up with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 43

Going ahead to step 6:
The number 43 fits into 59 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 3451.0
If we subtract 43 from 59, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
160 divided by 43 is 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 3451.3
Subtract 129 from 160 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
43 can be fit into 310 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 3451.37
Subtracting 301 from 310 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
43 goes into 90 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 3451.372
The remainder is 4 after subtracting 86 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
40 divided by 43 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3451.372
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
400 divided by 43 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 3451.37209
Deduct 387 from 400 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
When dividing 130 by 43, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3451.372093
If we subtract 129 from 130, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
If we divide 10 by 43, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 3451.372093
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
When dividing 100 by 43, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 3451.37209302
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 3451.37209302 with a remaining 1.4e-08.
