We're dividing 43102638 by 348 
We want to divide 43102638 by 348.

Moving on to step 1:
If we divide 4 by 348, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 348

Advancing to step 2:
If we divide 43 by 348, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 348

Advancing to step 3:
348 goes into 431 1 times with a remainder of 83.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 348 from 431 to get 83.
Include the next digit (0) from the dividend after 83, then repeat: 830 / 348

Step 4:
When dividing 830 by 348, we get 2 with a remainder of 134.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 696 from 830 and we're left with 134.
Bring next digit (2) of the dividend behind the 134 and repeat the process: 1342 / 348

Moving on to step 5:
The number 348 fits into 1342 3 times, leaving a remainder of 298.
Put 3 as the next digit of the answer. 
Result so far: 123.0
The remainder is 298 after subtracting 1044 from 1342.
Grab the next digit (6) from the dividend, add it to 298, then carry on: 2986 / 348

Let's proceed to step 6:
The number 348 fits into 2986 8 times, leaving a remainder of 202.
The next digit of our result is 8. 
Result so far: 1238.0
Subtract 2784 from 2986 to get 202.
Take the next digit (3) from the dividend and append it to 202, then repeat: 2023 / 348

Advancing to step 7:
If we divide 2023 by 348, we get 5 and a remainder of 283.
The number 5 becomes the next digit in our result. 
Result so far: 12385.0
If we subtract 1740 from 2023, we get 283.
Include the next digit (8) from the dividend after 283, then repeat: 2838 / 348

Let's proceed to step 8:
2838 divided by 348 is 8 with a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 123858.0
Subtracting 2784 from 2838 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
540 divided by 348 is 1 with a remainder of 192.
Record the quotient 1 as the next digit in the result. 
Result so far: 123858.1
If we subtract 348 from 540, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 10:
348 goes into 1920 5 times with a remainder of 180.
Put 5 as the next digit of the answer. 
Result so far: 123858.15
Subtract 1740 from 1920 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
If we divide 1800 by 348, we get 5 and a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 123858.155
If we take 1740 away from 1800, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 123858.155, and the remainder is 0.006.
