We divide 78407669 by 439
We want to divide 78407669 by 439.

Let's proceed to step 1:
7 divided by 439 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 439

Advancing to step 2:
When dividing 78 by 439, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 439

Moving on to step 3:
439 can be fit into 784 1 times, resulting in a remainder of 345.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 439 from 784 leaves us with 345.
Take the next digit (0) from the dividend and append it to 345, then repeat: 3450 / 439

Step 4:
If we divide 3450 by 439, we get 7 and a remainder of 377.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 3073 from 3450 leaves us with 377.
Take the next digit (7) from the dividend and append it to 377, then repeat: 3777 / 439

Step 5:
The number 439 fits into 3777 8 times, leaving a remainder of 265.
Write down 8 as next digit of the result. 
Result so far: 178.0
If we subtract 3512 from 3777, we get 265.
Bring next digit (6) of the dividend behind the 265 and repeat the process: 2656 / 439

Advancing to step 6:
The number 439 fits into 2656 6 times, leaving a remainder of 22.
The next digit of our result is 6. 
Result so far: 1786.0
If we subtract 2634 from 2656, we get 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 439

Going ahead to step 7:
226 divided by 439 is 0 with a remainder of 226.
The next digit of our result is 0. 
Result so far: 17860.0
Subtracting 0 from 226 leaves us with 226.
Take the next digit (9) from the dividend and append it to 226, then repeat: 2269 / 439

On to step 8:
439 goes into 2269 5 times with a remainder of 74.
Write down 5 as next digit of the result. 
Result so far: 178605.0
If we subtract 2195 from 2269, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
The number 439 fits into 740 1 times, leaving a remainder of 301.
The number 1 becomes the next digit in our result. 
Result so far: 178605.1
Subtracting 439 from 740 leaves us with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

On to step 10:
When dividing 3010 by 439, we get 6 with a remainder of 376.
The next digit of our result is 6. 
Result so far: 178605.16
Subtract 2634 from 3010 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 11:
If we divide 3760 by 439, we get 8 and a remainder of 248.
The next digit of our result is 8. 
Result so far: 178605.168
Subtracting 3512 from 3760 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 12:
439 can be fit into 2480 5 times, resulting in a remainder of 285.
The next digit of our result is 5. 
Result so far: 178605.1685
The remainder is 285 after subtracting 2195 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 13:
The number 439 fits into 2850 6 times, leaving a remainder of 216.
Put 6 as the next digit of the answer. 
Result so far: 178605.16856
If we subtract 2634 from 2850, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 14:
The number 439 fits into 2160 4 times, leaving a remainder of 404.
The number 4 becomes the next digit in our result. 
Result so far: 178605.168564
If we take 1756 away from 2160, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 15:
The number 439 fits into 4040 9 times, leaving a remainder of 89.
Write down 9 as next digit of the result. 
Result so far: 178605.1685649
If we subtract 3951 from 4040, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 16:
The number 439 fits into 890 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 178605.16856492
If we take 878 away from 890, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 178605.16856492, with a leftover of 1.2e-08.
