We divide 80671684 by 423
Let's see how many times 423 fits into 80671684.

Going ahead to step 1:
423 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
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 423

Step 2:
When dividing 80 by 423, we get 0 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.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 423

Going ahead to step 3:
The number 423 fits into 806 1 times, leaving a remainder of 383.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 423 from 806 and we're left with 383.
Include the next digit (7) from the dividend after 383, then repeat: 3837 / 423

On to step 4:
423 goes into 3837 9 times with a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 3807 from 3837 leaves us with 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 423

Advancing to step 5:
301 divided by 423 is 0 with a remainder of 301.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
If we subtract 0 from 301, we get 301.
Take the next digit (6) from the dividend and append it to 301, then repeat: 3016 / 423

Step 6:
If we divide 3016 by 423, we get 7 and a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 1907.0
Deduct 2961 from 3016 and we're left with 55.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 423

Moving on to step 7:
When dividing 558 by 423, we get 1 with a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 19071.0
Deduct 423 from 558 and we're left with 135.
Take the next digit (4) from the dividend and append it to 135, then repeat: 1354 / 423

Let's proceed to step 8:
423 goes into 1354 3 times with a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 190713.0
Deduct 1269 from 1354 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 9:
850 divided by 423 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 190713.2
Subtract 846 from 850 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
If we divide 40 by 423, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 190713.2
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
423 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 190713.2
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 190713.2 and a remainder of 0.04.
