78432076 divided by 809 
Our goal is to divide 78432076 by 809.

On to step 1:
The number 809 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 809

On to step 2:
If we divide 78 by 809, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 809

Advancing to step 3:
809 goes into 784 0 times with a remainder of 784.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 784 and we're left with 784.
Append the next digit (3) from the dividend to 784 and continue with: 7843 / 809

Going ahead to step 4:
The number 809 fits into 7843 9 times, leaving a remainder of 562.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 7281 from 7843 leaves us with 562.
Grab the next digit (2) from the dividend, add it to 562, then carry on: 5622 / 809

Going ahead to step 5:
The number 809 fits into 5622 6 times, leaving a remainder of 768.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we take 4854 away from 5622, we end up with 768.
Include the next digit (0) from the dividend after 768, then repeat: 7680 / 809

Step 6:
When dividing 7680 by 809, we get 9 with a remainder of 399.
The next digit of our result is 9. 
Result so far: 969.0
If we subtract 7281 from 7680, we get 399.
Bring next digit (7) of the dividend behind the 399 and repeat the process: 3997 / 809

On to step 7:
809 can be fit into 3997 4 times, resulting in a remainder of 761.
Put 4 as the next digit of the answer. 
Result so far: 9694.0
If we subtract 3236 from 3997, we get 761.
Take the next digit (6) from the dividend and append it to 761, then repeat: 7616 / 809

On to step 8:
809 can be fit into 7616 9 times, resulting in a remainder of 335.
The next digit of our result is 9. 
Result so far: 96949.0
Subtract 7281 from 7616 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 9:
809 goes into 3350 4 times with a remainder of 114.
Put 4 as the next digit of the answer. 
Result so far: 96949.4
Deduct 3236 from 3350 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 10:
809 goes into 1140 1 times with a remainder of 331.
Use 1 as the next digit of our solution. 
Result so far: 96949.41
The remainder is 331 after subtracting 809 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 11:
If we divide 3310 by 809, we get 4 and a remainder of 74.
The next digit of our result is 4. 
Result so far: 96949.414
The remainder is 74 after subtracting 3236 from 3310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 12:
809 goes into 740 0 times with a remainder of 740.
Write down 0 as next digit of the result. 
Result so far: 96949.414
If we subtract 0 from 740, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Moving on to step 13:
7400 divided by 809 is 9 with a remainder of 119.
The number 9 becomes the next digit in our result. 
Result so far: 96949.41409
The remainder is 119 after subtracting 7281 from 7400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 14:
809 goes into 1190 1 times with a remainder of 381.
Write down 1 as next digit of the result. 
Result so far: 96949.414091
If we subtract 809 from 1190, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Moving on to step 15:
809 can be fit into 3810 4 times, resulting in a remainder of 574.
The number 4 becomes the next digit in our result. 
Result so far: 96949.4140914
Deduct 3236 from 3810 and we're left with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Step 16:
The number 809 fits into 5740 7 times, leaving a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 96949.41409147
The remainder is 77 after subtracting 5663 from 5740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The quotient of the division is 96949.41409147, and the remainder is 7.7e-08.
