We're dividing 80517190 by 801 
We want to divide 80517190 by 801.

Advancing to step 1:
801 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 801

Step 2:
The number 801 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Bring next digit (5) of the dividend behind the 80 and repeat the process: 805 / 801

Step 3:
When dividing 805 by 801, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 801 away from 805, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 801

Moving on to step 4:
41 divided by 801 is 0 with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 41, we get 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 801

Let's proceed to step 5:
If we divide 417 by 801, we get 0 and a remainder of 417.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Deduct 0 from 417 and we're left with 417.
Bring next digit (1) of the dividend behind the 417 and repeat the process: 4171 / 801

On to step 6:
If we divide 4171 by 801, we get 5 and a remainder of 166.
Write down 5 as next digit of the result. 
Result so far: 1005.0
Subtracting 4005 from 4171 leaves us with 166.
Append the next digit (9) from the dividend to 166 and continue with: 1669 / 801

Step 7:
When dividing 1669 by 801, we get 2 with a remainder of 67.
Record the quotient 2 as the next digit in the result. 
Result so far: 10052.0
If we take 1602 away from 1669, we end up with 67.
Take the next digit (0) from the dividend and append it to 67, then repeat: 670 / 801

Advancing to step 8:
801 goes into 670 0 times with a remainder of 670.
The number 0 becomes the next digit in our result. 
Result so far: 100520.0
Subtract 0 from 670 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Let's proceed to step 9:
801 goes into 6700 8 times with a remainder of 292.
Use 8 as the next digit of our solution. 
Result so far: 100520.8
The remainder is 292 after subtracting 6408 from 6700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 10:
801 can be fit into 2920 3 times, resulting in a remainder of 517.
The number 3 becomes the next digit in our result. 
Result so far: 100520.83
Subtract 2403 from 2920 to get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Let's proceed to step 11:
801 can be fit into 5170 6 times, resulting in a remainder of 364.
Write down 6 as next digit of the result. 
Result so far: 100520.836
Deduct 4806 from 5170 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 12:
801 goes into 3640 4 times with a remainder of 436.
Record the quotient 4 as the next digit in the result. 
Result so far: 100520.8364
Deduct 3204 from 3640 and we're left with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Advancing to step 13:
If we divide 4360 by 801, we get 5 and a remainder of 355.
The next digit of our result is 5. 
Result so far: 100520.83645
If we take 4005 away from 4360, we end up with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Advancing to step 14:
When dividing 3550 by 801, we get 4 with a remainder of 346.
Use 4 as the next digit of our solution. 
Result so far: 100520.836454
If we take 3204 away from 3550, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 15:
801 goes into 3460 4 times with a remainder of 256.
Record the quotient 4 as the next digit in the result. 
Result so far: 100520.8364544
If we subtract 3204 from 3460, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The quotient of the division is 100520.8364544, and the remainder is 2.56e-06.
