79580631 divided by 801 
We want to divide 79580631 by 801.

Let's proceed to step 1:
801 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 801

Step 2:
79 divided by 801 is 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Append the next digit (5) from the dividend to 79 and continue with: 795 / 801

Step 3:
When dividing 795 by 801, we get 0 with a remainder of 795.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 795, we get 795.
Grab the next digit (8) from the dividend, add it to 795, then carry on: 7958 / 801

Moving on to step 4:
If we divide 7958 by 801, we get 9 and a remainder of 749.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 7209 from 7958 and we're left with 749.
Bring next digit (0) of the dividend behind the 749 and repeat the process: 7490 / 801

On to step 5:
801 can be fit into 7490 9 times, resulting in a remainder of 281.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Deduct 7209 from 7490 and we're left with 281.
Take the next digit (6) from the dividend and append it to 281, then repeat: 2816 / 801

On to step 6:
801 can be fit into 2816 3 times, resulting in a remainder of 413.
Record the quotient 3 as the next digit in the result. 
Result so far: 993.0
If we subtract 2403 from 2816, we get 413.
Grab the next digit (3) from the dividend, add it to 413, then carry on: 4133 / 801

Advancing to step 7:
When dividing 4133 by 801, we get 5 with a remainder of 128.
Use 5 as the next digit of our solution. 
Result so far: 9935.0
If we take 4005 away from 4133, we end up with 128.
Include the next digit (1) from the dividend after 128, then repeat: 1281 / 801

Let's proceed to step 8:
801 can be fit into 1281 1 times, resulting in a remainder of 480.
Use 1 as the next digit of our solution. 
Result so far: 99351.0
The remainder is 480 after subtracting 801 from 1281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 9:
801 goes into 4800 5 times with a remainder of 795.
Record the quotient 5 as the next digit in the result. 
Result so far: 99351.5
Deduct 4005 from 4800 and we're left with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Let's proceed to step 10:
The number 801 fits into 7950 9 times, leaving a remainder of 741.
The number 9 becomes the next digit in our result. 
Result so far: 99351.59
Subtracting 7209 from 7950 leaves us with 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Let's proceed to step 11:
If we divide 7410 by 801, we get 9 and a remainder of 201.
The number 9 becomes the next digit in our result. 
Result so far: 99351.599
Subtract 7209 from 7410 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

The final result is 99351.599 with a remainder of 0.0201.
