We look at the division of 673978 by 64 
We want to figure out the number of times 673978 can be divided by 64.

Step 1:
64 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 64

Step 2:
The number 64 fits into 67 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 64 from 67 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 64

Step 3:
64 can be fit into 33 0 times, resulting in a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 33, we get 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 64

Step 4:
If we divide 339 by 64, we get 5 and a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we subtract 320 from 339, we get 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 64

Going ahead to step 5:
64 goes into 197 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 1053.0
The remainder is 5 after subtracting 192 from 197.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 64

Advancing to step 6:
The number 64 fits into 58 0 times, leaving a remainder of 58.
The next digit of our result is 0. 
Result so far: 10530.0
The remainder is 58 after subtracting 0 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 7:
The number 64 fits into 580 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 10530.9
Subtracting 576 from 580 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 64 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10530.9
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
400 divided by 64 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 10530.906
Subtracting 384 from 400 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
64 goes into 160 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 10530.9062
The remainder is 32 after subtracting 128 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
64 can be fit into 320 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10530.90625
The remainder is 0 after subtracting 320 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10530.90625
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10530.90625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 10530.90625 with a balance of 0.0.
