We're dividing 43721348 by 523 
Our goal is to divide 43721348 by 523.

Advancing to step 1:
When dividing 4 by 523, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 523

Let's proceed to step 2:
43 divided by 523 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (7) from the dividend and append it to 43, then repeat: 437 / 523

On to step 3:
523 can be fit into 437 0 times, resulting in a remainder of 437.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 437 after subtracting 0 from 437.
Include the next digit (2) from the dividend after 437, then repeat: 4372 / 523

Advancing to step 4:
523 can be fit into 4372 8 times, resulting in a remainder of 188.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 4184 from 4372, we get 188.
Fetch the next digit (1) from the dividend, attach it to 188 and continue: 1881 / 523

Let's proceed to step 5:
When dividing 1881 by 523, we get 3 with a remainder of 312.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtract 1569 from 1881 to get 312.
Take the next digit (3) from the dividend and append it to 312, then repeat: 3123 / 523

Step 6:
3123 divided by 523 is 5 with a remainder of 508.
The number 5 becomes the next digit in our result. 
Result so far: 835.0
If we subtract 2615 from 3123, we get 508.
Append the next digit (4) from the dividend to 508 and continue with: 5084 / 523

Let's proceed to step 7:
523 can be fit into 5084 9 times, resulting in a remainder of 377.
Use 9 as the next digit of our solution. 
Result so far: 8359.0
If we take 4707 away from 5084, we end up with 377.
Bring next digit (8) of the dividend behind the 377 and repeat the process: 3778 / 523

On to step 8:
If we divide 3778 by 523, we get 7 and a remainder of 117.
Record the quotient 7 as the next digit in the result. 
Result so far: 83597.0
Deduct 3661 from 3778 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 9:
523 can be fit into 1170 2 times, resulting in a remainder of 124.
The next digit of our result is 2. 
Result so far: 83597.2
Deduct 1046 from 1170 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 10:
523 goes into 1240 2 times with a remainder of 194.
The number 2 becomes the next digit in our result. 
Result so far: 83597.22
Deduct 1046 from 1240 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

The final result is 83597.22 with a remainder of 0.194.
