801319 divided by 90 
Our goal is to divide 801319 by 90.

On to step 1:
90 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 90

Going ahead to step 2:
The number 90 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Grab the next digit (1) from the dividend, add it to 80, then carry on: 801 / 90

Step 3:
90 can be fit into 801 8 times, resulting in a remainder of 81.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 720 away from 801, we end up with 81.
Grab the next digit (3) from the dividend, add it to 81, then carry on: 813 / 90

On to step 4:
90 can be fit into 813 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we take 810 away from 813, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 90

Moving on to step 5:
If we divide 31 by 90, we get 0 and a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 890.0
Subtract 0 from 31 to get 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 90

On to step 6:
90 can be fit into 319 3 times, resulting in a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 8903.0
Subtract 270 from 319 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
When dividing 490 by 90, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 8903.5
Deduct 450 from 490 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
400 divided by 90 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 8903.54
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
When dividing 400 by 90, we get 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 8903.544
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 8903.544 and a remainder of 0.004.
