43070459 ÷ 104 
We want to divide 43070459 by 104.

Moving on to step 1:
104 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 104

On to step 2:
104 can be fit into 43 0 times, resulting in a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 104

Advancing to step 3:
The number 104 fits into 430 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 416 from 430 and we're left with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 104

Let's proceed to step 4:
104 goes into 147 1 times with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 41.0
The remainder is 43 after subtracting 104 from 147.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 104

On to step 5:
The number 104 fits into 430 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 414.0
Deduct 416 from 430 and we're left with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 104

Going ahead to step 6:
The number 104 fits into 144 1 times, leaving a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 4141.0
If we take 104 away from 144, we end up with 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 104

Advancing to step 7:
104 goes into 405 3 times with a remainder of 93.
The number 3 becomes the next digit in our result. 
Result so far: 41413.0
The remainder is 93 after subtracting 312 from 405.
Fetch the next digit (9) from the dividend, attach it to 93 and continue: 939 / 104

Advancing to step 8:
When dividing 939 by 104, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 414139.0
The remainder is 3 after subtracting 936 from 939.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
104 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 414139.0
Subtracting 0 from 30 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.

Let's proceed to step 10:
The number 104 fits into 300 2 times, leaving a remainder of 92.
Write down 2 as next digit of the result. 
Result so far: 414139.02
Subtracting 208 from 300 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 11:
When dividing 920 by 104, we get 8 with a remainder of 88.
The next digit of our result is 8. 
Result so far: 414139.028
Subtract 832 from 920 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 12:
When dividing 880 by 104, we get 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 414139.0288
If we take 832 away from 880, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 414139.0288, and the remainder is 0.00048.
