74824470 ÷ 820 
Our goal is to divide 74824470 by 820.

On to step 1:
The number 820 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 820

Let's proceed to step 2:
74 divided by 820 is 0 with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 820

Moving on to step 3:
If we divide 748 by 820, we get 0 and a remainder of 748.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 748 to get 748.
Bring next digit (2) of the dividend behind the 748 and repeat the process: 7482 / 820

Advancing to step 4:
The number 820 fits into 7482 9 times, leaving a remainder of 102.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 7380 from 7482 leaves us with 102.
Fetch the next digit (4) from the dividend, attach it to 102 and continue: 1024 / 820

Step 5:
1024 divided by 820 is 1 with a remainder of 204.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Deduct 820 from 1024 and we're left with 204.
Take the next digit (4) from the dividend and append it to 204, then repeat: 2044 / 820

Going ahead to step 6:
820 can be fit into 2044 2 times, resulting in a remainder of 404.
Put 2 as the next digit of the answer. 
Result so far: 912.0
Deduct 1640 from 2044 and we're left with 404.
Include the next digit (7) from the dividend after 404, then repeat: 4047 / 820

Let's proceed to step 7:
When dividing 4047 by 820, we get 4 with a remainder of 767.
The number 4 becomes the next digit in our result. 
Result so far: 9124.0
Subtract 3280 from 4047 to get 767.
Grab the next digit (0) from the dividend, add it to 767, then carry on: 7670 / 820

Step 8:
820 goes into 7670 9 times with a remainder of 290.
The next digit of our result is 9. 
Result so far: 91249.0
If we subtract 7380 from 7670, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 9:
820 goes into 2900 3 times with a remainder of 440.
The next digit of our result is 3. 
Result so far: 91249.3
Subtract 2460 from 2900 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 10:
If we divide 4400 by 820, we get 5 and a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 91249.35
Subtract 4100 from 4400 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
When dividing 3000 by 820, we get 3 with a remainder of 540.
The next digit of our result is 3. 
Result so far: 91249.353
Subtract 2460 from 3000 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 12:
820 can be fit into 5400 6 times, resulting in a remainder of 480.
Write down 6 as next digit of the result. 
Result so far: 91249.3536
Subtracting 4920 from 5400 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 13:
The number 820 fits into 4800 5 times, leaving a remainder of 700.
Use 5 as the next digit of our solution. 
Result so far: 91249.35365
The remainder is 700 after subtracting 4100 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 14:
7000 divided by 820 is 8 with a remainder of 440.
The next digit of our result is 8. 
Result so far: 91249.353658
Subtract 6560 from 7000 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 15:
If we divide 4400 by 820, we get 5 and a remainder of 300.
The next digit of our result is 5. 
Result so far: 91249.3536585
The remainder is 300 after subtracting 4100 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 16:
If we divide 3000 by 820, we get 3 and a remainder of 540.
Write down 3 as next digit of the result. 
Result so far: 91249.35365853
If we subtract 2460 from 3000, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Our division results in 91249.35365853 with a remaining 5.4e-07.
