We look at the division of 78394992 by 664 
We want to figure out the number of times 78394992 can be divided by 664.

Moving on to step 1:
664 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 664

Let's proceed to step 2:
The number 664 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 664

Advancing to step 3:
If we divide 783 by 664, we get 1 and a remainder of 119.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 664 from 783 and we're left with 119.
Append the next digit (9) from the dividend to 119 and continue with: 1199 / 664

Step 4:
664 goes into 1199 1 times with a remainder of 535.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 535 after subtracting 664 from 1199.
Include the next digit (4) from the dividend after 535, then repeat: 5354 / 664

On to step 5:
5354 divided by 664 is 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Subtracting 5312 from 5354 leaves us with 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 664

Moving on to step 6:
664 can be fit into 429 0 times, resulting in a remainder of 429.
Write down 0 as next digit of the result. 
Result so far: 1180.0
Subtracting 0 from 429 leaves us with 429.
Append the next digit (9) from the dividend to 429 and continue with: 4299 / 664

Let's proceed to step 7:
664 can be fit into 4299 6 times, resulting in a remainder of 315.
Write down 6 as next digit of the result. 
Result so far: 11806.0
Subtract 3984 from 4299 to get 315.
Append the next digit (2) from the dividend to 315 and continue with: 3152 / 664

Step 8:
If we divide 3152 by 664, we get 4 and a remainder of 496.
Use 4 as the next digit of our solution. 
Result so far: 118064.0
Deduct 2656 from 3152 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 9:
If we divide 4960 by 664, we get 7 and a remainder of 312.
The number 7 becomes the next digit in our result. 
Result so far: 118064.7
Deduct 4648 from 4960 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 10:
664 goes into 3120 4 times with a remainder of 464.
Write down 4 as next digit of the result. 
Result so far: 118064.74
Deduct 2656 from 3120 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 11:
If we divide 4640 by 664, we get 6 and a remainder of 656.
Record the quotient 6 as the next digit in the result. 
Result so far: 118064.746
Deduct 3984 from 4640 and we're left with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 12:
If we divide 6560 by 664, we get 9 and a remainder of 584.
Use 9 as the next digit of our solution. 
Result so far: 118064.7469
If we subtract 5976 from 6560, we get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Let's proceed to step 13:
664 can be fit into 5840 8 times, resulting in a remainder of 528.
The number 8 becomes the next digit in our result. 
Result so far: 118064.74698
Subtracting 5312 from 5840 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Advancing to step 14:
5280 divided by 664 is 7 with a remainder of 632.
The next digit of our result is 7. 
Result so far: 118064.746987
Subtracting 4648 from 5280 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Moving on to step 15:
664 can be fit into 6320 9 times, resulting in a remainder of 344.
The next digit of our result is 9. 
Result so far: 118064.7469879
If we take 5976 away from 6320, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 16:
664 goes into 3440 5 times with a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 118064.74698795
The remainder is 120 after subtracting 3320 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 118064.74698795 with a balance of 1.2e-07.
