80840269 ÷ 903 
We want to figure out the number of times 80840269 can be divided by 903.

Advancing to step 1:
8 divided by 903 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 903

On to step 2:
80 divided by 903 is 0 with 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 (8) of the dividend behind the 80 and repeat the process: 808 / 903

On to step 3:
When dividing 808 by 903, we get 0 with a remainder of 808.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 808, we get 808.
Take the next digit (4) from the dividend and append it to 808, then repeat: 8084 / 903

Let's proceed to step 4:
8084 divided by 903 is 8 with a remainder of 860.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 7224 from 8084, we get 860.
Fetch the next digit (0) from the dividend, attach it to 860 and continue: 8600 / 903

On to step 5:
The number 903 fits into 8600 9 times, leaving a remainder of 473.
Put 9 as the next digit of the answer. 
Result so far: 89.0
Subtract 8127 from 8600 to get 473.
Grab the next digit (2) from the dividend, add it to 473, then carry on: 4732 / 903

Step 6:
When dividing 4732 by 903, we get 5 with a remainder of 217.
Use 5 as the next digit of our solution. 
Result so far: 895.0
Deduct 4515 from 4732 and we're left with 217.
Grab the next digit (6) from the dividend, add it to 217, then carry on: 2176 / 903

Advancing to step 7:
903 goes into 2176 2 times with a remainder of 370.
Record the quotient 2 as the next digit in the result. 
Result so far: 8952.0
If we subtract 1806 from 2176, we get 370.
Take the next digit (9) from the dividend and append it to 370, then repeat: 3709 / 903

On to step 8:
903 can be fit into 3709 4 times, resulting in a remainder of 97.
Use 4 as the next digit of our solution. 
Result so far: 89524.0
If we take 3612 away from 3709, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 9:
903 goes into 970 1 times with a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 89524.1
Subtract 903 from 970 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 10:
670 divided by 903 is 0 with a remainder of 670.
The next digit of our result is 0. 
Result so far: 89524.1
If we subtract 0 from 670, we 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.

Step 11:
6700 divided by 903 is 7 with a remainder of 379.
The number 7 becomes the next digit in our result. 
Result so far: 89524.107
Subtracting 6321 from 6700 leaves us with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Going ahead to step 12:
903 can be fit into 3790 4 times, resulting in a remainder of 178.
Use 4 as the next digit of our solution. 
Result so far: 89524.1074
The remainder is 178 after subtracting 3612 from 3790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 13:
If we divide 1780 by 903, we get 1 and a remainder of 877.
Put 1 as the next digit of the answer. 
Result so far: 89524.10741
Subtracting 903 from 1780 leaves us with 877.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8770, and continue the process.

On to step 14:
903 can be fit into 8770 9 times, resulting in a remainder of 643.
Put 9 as the next digit of the answer. 
Result so far: 89524.107419
Subtract 8127 from 8770 to get 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Going ahead to step 15:
903 can be fit into 6430 7 times, resulting in a remainder of 109.
The next digit of our result is 7. 
Result so far: 89524.1074197
Deduct 6321 from 6430 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 16:
903 can be fit into 1090 1 times, resulting in a remainder of 187.
The next digit of our result is 1. 
Result so far: 89524.10741971
If we take 903 away from 1090, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

The final outcome is 89524.10741971, with a leftover of 1.87e-07.
