74704452 ÷ 820 
Our goal is to divide 74704452 by 820.

Going ahead to step 1:
If we divide 7 by 820, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 820

Let's proceed to step 2:
820 can be fit into 74 0 times, resulting in a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Include the next digit (7) from the dividend after 74, then repeat: 747 / 820

Moving on to step 3:
The number 820 fits into 747 0 times, leaving a remainder of 747.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 747, we get 747.
Bring next digit (0) of the dividend behind the 747 and repeat the process: 7470 / 820

Advancing to step 4:
The number 820 fits into 7470 9 times, leaving a remainder of 90.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7380 from 7470 leaves us with 90.
Include the next digit (4) from the dividend after 90, then repeat: 904 / 820

On to step 5:
820 can be fit into 904 1 times, resulting in a remainder of 84.
The next digit of our result is 1. 
Result so far: 91.0
If we take 820 away from 904, we end up with 84.
Include the next digit (4) from the dividend after 84, then repeat: 844 / 820

Let's proceed to step 6:
820 can be fit into 844 1 times, resulting in a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 911.0
Deduct 820 from 844 and we're left with 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 820

Let's proceed to step 7:
820 can be fit into 245 0 times, resulting in a remainder of 245.
The next digit of our result is 0. 
Result so far: 9110.0
Subtract 0 from 245 to get 245.
Append the next digit (2) from the dividend to 245 and continue with: 2452 / 820

Step 8:
820 goes into 2452 2 times with a remainder of 812.
Use 2 as the next digit of our solution. 
Result so far: 91102.0
If we subtract 1640 from 2452, we get 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Let's proceed to step 9:
If we divide 8120 by 820, we get 9 and a remainder of 740.
Write down 9 as next digit of the result. 
Result so far: 91102.9
The remainder is 740 after subtracting 7380 from 8120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 10:
820 goes into 7400 9 times with a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 91102.99
Subtracting 7380 from 7400 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 91102.99, with a leftover of 0.02.
