We're dividing 80018309 by 898 
Our goal is to divide 80018309 by 898.

Step 1:
8 divided by 898 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 898

Let's proceed to step 2:
898 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Fetch the next digit (0) from the dividend, attach it to 80 and continue: 800 / 898

Moving on to step 3:
When dividing 800 by 898, we get 0 with a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 800 after subtracting 0 from 800.
Append the next digit (1) from the dividend to 800 and continue with: 8001 / 898

Advancing to step 4:
8001 divided by 898 is 8 with a remainder of 817.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 7184 from 8001, we get 817.
Fetch the next digit (8) from the dividend, attach it to 817 and continue: 8178 / 898

On to step 5:
8178 divided by 898 is 9 with a remainder of 96.
The next digit of our result is 9. 
Result so far: 89.0
Subtract 8082 from 8178 to get 96.
Grab the next digit (3) from the dividend, add it to 96, then carry on: 963 / 898

Advancing to step 6:
When dividing 963 by 898, we get 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 891.0
Subtracting 898 from 963 leaves us with 65.
Append the next digit (0) from the dividend to 65 and continue with: 650 / 898

Step 7:
650 divided by 898 is 0 with a remainder of 650.
Put 0 as the next digit of the answer. 
Result so far: 8910.0
If we subtract 0 from 650, we get 650.
Take the next digit (9) from the dividend and append it to 650, then repeat: 6509 / 898

Advancing to step 8:
When dividing 6509 by 898, we get 7 with a remainder of 223.
The next digit of our result is 7. 
Result so far: 89107.0
Subtracting 6286 from 6509 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 9:
898 can be fit into 2230 2 times, resulting in a remainder of 434.
Put 2 as the next digit of the answer. 
Result so far: 89107.2
If we subtract 1796 from 2230, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 10:
898 can be fit into 4340 4 times, resulting in a remainder of 748.
Put 4 as the next digit of the answer. 
Result so far: 89107.24
The remainder is 748 after subtracting 3592 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Going ahead to step 11:
7480 divided by 898 is 8 with a remainder of 296.
Put 8 as the next digit of the answer. 
Result so far: 89107.248
Subtract 7184 from 7480 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 12:
898 goes into 2960 3 times with a remainder of 266.
Record the quotient 3 as the next digit in the result. 
Result so far: 89107.2483
Subtracting 2694 from 2960 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 13:
898 goes into 2660 2 times with a remainder of 864.
Use 2 as the next digit of our solution. 
Result so far: 89107.24832
The remainder is 864 after subtracting 1796 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

On to step 14:
8640 divided by 898 is 9 with a remainder of 558.
Write down 9 as next digit of the result. 
Result so far: 89107.248329
Deduct 8082 from 8640 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Step 15:
898 goes into 5580 6 times with a remainder of 192.
Record the quotient 6 as the next digit in the result. 
Result so far: 89107.2483296
Subtracting 5388 from 5580 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 16:
898 can be fit into 1920 2 times, resulting in a remainder of 124.
The number 2 becomes the next digit in our result. 
Result so far: 89107.24832962
Subtracting 1796 from 1920 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final outcome is 89107.24832962, with a leftover of 1.24e-07.
