We're dividing 80154871 by 424 
We want to divide 80154871 by 424.

Step 1:
424 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 424

Step 2:
424 goes into 80 0 times with 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.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 424

Advancing to step 3:
The number 424 fits into 801 1 times, leaving a remainder of 377.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 424 from 801 and we're left with 377.
Fetch the next digit (5) from the dividend, attach it to 377 and continue: 3775 / 424

Going ahead to step 4:
424 can be fit into 3775 8 times, resulting in a remainder of 383.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 3392 from 3775 and we're left with 383.
Append the next digit (4) from the dividend to 383 and continue with: 3834 / 424

On to step 5:
3834 divided by 424 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 189.0
The remainder is 18 after subtracting 3816 from 3834.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 424

Let's proceed to step 6:
424 goes into 188 0 times with a remainder of 188.
The next digit of our result is 0. 
Result so far: 1890.0
Subtracting 0 from 188 leaves us with 188.
Append the next digit (7) from the dividend to 188 and continue with: 1887 / 424

Let's proceed to step 7:
The number 424 fits into 1887 4 times, leaving a remainder of 191.
The next digit of our result is 4. 
Result so far: 18904.0
Deduct 1696 from 1887 and we're left with 191.
Bring next digit (1) of the dividend behind the 191 and repeat the process: 1911 / 424

On to step 8:
If we divide 1911 by 424, we get 4 and a remainder of 215.
Put 4 as the next digit of the answer. 
Result so far: 189044.0
If we take 1696 away from 1911, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 9:
424 goes into 2150 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 189044.5
Subtract 2120 from 2150 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
424 goes into 300 0 times with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 189044.5
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
424 goes into 3000 7 times with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 189044.507
Subtracting 2968 from 3000 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.

Let's proceed to step 12:
When dividing 320 by 424, we get 0 with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 189044.507
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 13:
424 can be fit into 3200 7 times, resulting in a remainder of 232.
Put 7 as the next digit of the answer. 
Result so far: 189044.50707
The remainder is 232 after subtracting 2968 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 14:
424 goes into 2320 5 times with a remainder of 200.
The next digit of our result is 5. 
Result so far: 189044.507075
Subtracting 2120 from 2320 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 15:
2000 divided by 424 is 4 with a remainder of 304.
Write down 4 as next digit of the result. 
Result so far: 189044.5070754
If we take 1696 away from 2000, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 16:
When dividing 3040 by 424, we get 7 with a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 189044.50707547
Subtract 2968 from 3040 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 189044.50707547, and the remainder is 7.2e-08.
