We look at the division of 80363415 by 583 
We want to divide 80363415 by 583.

Advancing to step 1:
583 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 583

On to step 2:
583 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 583

Going ahead to step 3:
583 goes into 803 1 times with a remainder of 220.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 583 from 803 leaves us with 220.
Fetch the next digit (6) from the dividend, attach it to 220 and continue: 2206 / 583

Going ahead to step 4:
583 can be fit into 2206 3 times, resulting in a remainder of 457.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1749 away from 2206, we end up with 457.
Include the next digit (3) from the dividend after 457, then repeat: 4573 / 583

Let's proceed to step 5:
If we divide 4573 by 583, we get 7 and a remainder of 492.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Deduct 4081 from 4573 and we're left with 492.
Grab the next digit (4) from the dividend, add it to 492, then carry on: 4924 / 583

Step 6:
When dividing 4924 by 583, we get 8 with a remainder of 260.
Write down 8 as next digit of the result. 
Result so far: 1378.0
If we take 4664 away from 4924, we end up with 260.
Fetch the next digit (1) from the dividend, attach it to 260 and continue: 2601 / 583

Going ahead to step 7:
If we divide 2601 by 583, we get 4 and a remainder of 269.
Use 4 as the next digit of our solution. 
Result so far: 13784.0
If we subtract 2332 from 2601, we get 269.
Bring next digit (5) of the dividend behind the 269 and repeat the process: 2695 / 583

Moving on to step 8:
583 goes into 2695 4 times with a remainder of 363.
Use 4 as the next digit of our solution. 
Result so far: 137844.0
Subtract 2332 from 2695 to get 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Advancing to step 9:
When dividing 3630 by 583, we get 6 with a remainder of 132.
Write down 6 as next digit of the result. 
Result so far: 137844.6
If we subtract 3498 from 3630, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 10:
The number 583 fits into 1320 2 times, leaving a remainder of 154.
Record the quotient 2 as the next digit in the result. 
Result so far: 137844.62
Deduct 1166 from 1320 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 11:
1540 divided by 583 is 2 with a remainder of 374.
The number 2 becomes the next digit in our result. 
Result so far: 137844.622
If we subtract 1166 from 1540, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Our division results in 137844.622 with a remaining 0.0374.
