78319838 divided by 647 
We want to figure out the number of times 78319838 can be divided by 647.

Moving on to step 1:
647 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 647

Let's proceed to step 2:
78 divided by 647 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 647

Advancing to step 3:
647 goes into 783 1 times with a remainder of 136.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 647 away from 783, we end up with 136.
Take the next digit (1) from the dividend and append it to 136, then repeat: 1361 / 647

Step 4:
When dividing 1361 by 647, we get 2 with a remainder of 67.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1294 from 1361, we get 67.
Append the next digit (9) from the dividend to 67 and continue with: 679 / 647

On to step 5:
The number 647 fits into 679 1 times, leaving a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
If we take 647 away from 679, we end up with 32.
Take the next digit (8) from the dividend and append it to 32, then repeat: 328 / 647

Let's proceed to step 6:
When dividing 328 by 647, we get 0 with a remainder of 328.
Write down 0 as next digit of the result. 
Result so far: 1210.0
If we subtract 0 from 328, we get 328.
Bring next digit (3) of the dividend behind the 328 and repeat the process: 3283 / 647

Going ahead to step 7:
When dividing 3283 by 647, we get 5 with a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 12105.0
If we subtract 3235 from 3283, we get 48.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 647

On to step 8:
If we divide 488 by 647, we get 0 and a remainder of 488.
Use 0 as the next digit of our solution. 
Result so far: 121050.0
Subtract 0 from 488 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 9:
If we divide 4880 by 647, we get 7 and a remainder of 351.
Put 7 as the next digit of the answer. 
Result so far: 121050.7
Subtracting 4529 from 4880 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Step 10:
647 goes into 3510 5 times with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 121050.75
Deduct 3235 from 3510 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 11:
When dividing 2750 by 647, we get 4 with a remainder of 162.
The number 4 becomes the next digit in our result. 
Result so far: 121050.754
Subtracting 2588 from 2750 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 12:
1620 divided by 647 is 2 with a remainder of 326.
Use 2 as the next digit of our solution. 
Result so far: 121050.7542
Subtracting 1294 from 1620 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Moving on to step 13:
647 can be fit into 3260 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 121050.75425
Subtract 3235 from 3260 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
If we divide 250 by 647, we get 0 and a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 121050.75425
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 15:
2500 divided by 647 is 3 with a remainder of 559.
Record the quotient 3 as the next digit in the result. 
Result so far: 121050.7542503
The remainder is 559 after subtracting 1941 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Advancing to step 16:
The number 647 fits into 5590 8 times, leaving a remainder of 414.
The number 8 becomes the next digit in our result. 
Result so far: 121050.75425038
Subtract 5176 from 5590 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

In conclusion, the division gives 121050.75425038 with a balance of 4.14e-07.
