30839729 ÷ 801 
Let's see how many times 801 fits into 30839729.

On to step 1:
When dividing 3 by 801, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 801

Moving on to step 2:
801 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 801

Let's proceed to step 3:
801 goes into 308 0 times with a remainder of 308.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 308 after subtracting 0 from 308.
Take the next digit (3) from the dividend and append it to 308, then repeat: 3083 / 801

Advancing to step 4:
3083 divided by 801 is 3 with a remainder of 680.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 2403 from 3083 leaves us with 680.
Include the next digit (9) from the dividend after 680, then repeat: 6809 / 801

On to step 5:
The number 801 fits into 6809 8 times, leaving a remainder of 401.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtract 6408 from 6809 to get 401.
Take the next digit (7) from the dividend and append it to 401, then repeat: 4017 / 801

Let's proceed to step 6:
When dividing 4017 by 801, we get 5 with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 385.0
If we take 4005 away from 4017, we end up with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 801

On to step 7:
The number 801 fits into 122 0 times, leaving a remainder of 122.
The next digit of our result is 0. 
Result so far: 3850.0
Deduct 0 from 122 and we're left with 122.
Take the next digit (9) from the dividend and append it to 122, then repeat: 1229 / 801

Going ahead to step 8:
The number 801 fits into 1229 1 times, leaving a remainder of 428.
The number 1 becomes the next digit in our result. 
Result so far: 38501.0
Deduct 801 from 1229 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 9:
4280 divided by 801 is 5 with a remainder of 275.
The next digit of our result is 5. 
Result so far: 38501.5
Subtract 4005 from 4280 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 10:
801 goes into 2750 3 times with a remainder of 347.
The next digit of our result is 3. 
Result so far: 38501.53
Subtract 2403 from 2750 to get 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Advancing to step 11:
3470 divided by 801 is 4 with a remainder of 266.
Put 4 as the next digit of the answer. 
Result so far: 38501.534
If we take 3204 away from 3470, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 12:
If we divide 2660 by 801, we get 3 and a remainder of 257.
The number 3 becomes the next digit in our result. 
Result so far: 38501.5343
Deduct 2403 from 2660 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 13:
When dividing 2570 by 801, we get 3 with a remainder of 167.
The next digit of our result is 3. 
Result so far: 38501.53433
Subtracting 2403 from 2570 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

After the division, we end up with 38501.53433 and a remainder of 0.000167.
