Let's divide 80899958 by 503
We want to divide 80899958 by 503.

Going ahead to step 1:
The number 503 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 503

Step 2:
If we divide 80 by 503, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 503

On to step 3:
808 divided by 503 is 1 with a remainder of 305.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 503 from 808 leaves us with 305.
Take the next digit (9) from the dividend and append it to 305, then repeat: 3059 / 503

Advancing to step 4:
If we divide 3059 by 503, we get 6 and a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 3018 from 3059 and we're left with 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 503

On to step 5:
The number 503 fits into 419 0 times, leaving a remainder of 419.
Put 0 as the next digit of the answer. 
Result so far: 160.0
The remainder is 419 after subtracting 0 from 419.
Include the next digit (9) from the dividend after 419, then repeat: 4199 / 503

On to step 6:
503 goes into 4199 8 times with a remainder of 175.
Use 8 as the next digit of our solution. 
Result so far: 1608.0
Deduct 4024 from 4199 and we're left with 175.
Grab the next digit (5) from the dividend, add it to 175, then carry on: 1755 / 503

Going ahead to step 7:
When dividing 1755 by 503, we get 3 with a remainder of 246.
Write down 3 as next digit of the result. 
Result so far: 16083.0
If we subtract 1509 from 1755, we get 246.
Fetch the next digit (8) from the dividend, attach it to 246 and continue: 2468 / 503

Going ahead to step 8:
When dividing 2468 by 503, we get 4 with a remainder of 456.
The number 4 becomes the next digit in our result. 
Result so far: 160834.0
The remainder is 456 after subtracting 2012 from 2468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 9:
If we divide 4560 by 503, we get 9 and a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 160834.9
Deduct 4527 from 4560 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
330 divided by 503 is 0 with a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 160834.9
Deduct 0 from 330 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 11:
The number 503 fits into 3300 6 times, leaving a remainder of 282.
The number 6 becomes the next digit in our result. 
Result so far: 160834.906
Subtracting 3018 from 3300 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 12:
503 can be fit into 2820 5 times, resulting in a remainder of 305.
Put 5 as the next digit of the answer. 
Result so far: 160834.9065
If we subtract 2515 from 2820, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 13:
If we divide 3050 by 503, we get 6 and a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 160834.90656
Subtracting 3018 from 3050 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
320 divided by 503 is 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 160834.90656
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 15:
3200 divided by 503 is 6 with a remainder of 182.
The next digit of our result is 6. 
Result so far: 160834.9065606
Deduct 3018 from 3200 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 16:
503 can be fit into 1820 3 times, resulting in a remainder of 311.
Record the quotient 3 as the next digit in the result. 
Result so far: 160834.90656063
If we subtract 1509 from 1820, we get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

The final result is 160834.90656063 with a remainder of 3.11e-07.
