Let's divide 64107554 by 860
We want to figure out the number of times 64107554 can be divided by 860.

Step 1:
6 divided by 860 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 860

Moving on to step 2:
64 divided by 860 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 860

Step 3:
860 goes into 641 0 times with a remainder of 641.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 641, we get 641.
Fetch the next digit (0) from the dividend, attach it to 641 and continue: 6410 / 860

Moving on to step 4:
If we divide 6410 by 860, we get 7 and a remainder of 390.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 6020 from 6410 leaves us with 390.
Take the next digit (7) from the dividend and append it to 390, then repeat: 3907 / 860

On to step 5:
If we divide 3907 by 860, we get 4 and a remainder of 467.
The next digit of our result is 4. 
Result so far: 74.0
Deduct 3440 from 3907 and we're left with 467.
Include the next digit (5) from the dividend after 467, then repeat: 4675 / 860

Going ahead to step 6:
4675 divided by 860 is 5 with a remainder of 375.
The next digit of our result is 5. 
Result so far: 745.0
If we subtract 4300 from 4675, we get 375.
Bring next digit (5) of the dividend behind the 375 and repeat the process: 3755 / 860

Let's proceed to step 7:
860 goes into 3755 4 times with a remainder of 315.
Put 4 as the next digit of the answer. 
Result so far: 7454.0
Subtracting 3440 from 3755 leaves us with 315.
Include the next digit (4) from the dividend after 315, then repeat: 3154 / 860

Advancing to step 8:
When dividing 3154 by 860, we get 3 with a remainder of 574.
The next digit of our result is 3. 
Result so far: 74543.0
Subtracting 2580 from 3154 leaves us 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.

On to step 9:
If we divide 5740 by 860, we get 6 and a remainder of 580.
Record the quotient 6 as the next digit in the result. 
Result so far: 74543.6
Subtract 5160 from 5740 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 10:
5800 divided by 860 is 6 with a remainder of 640.
The number 6 becomes the next digit in our result. 
Result so far: 74543.66
Subtract 5160 from 5800 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The quotient of the division is 74543.66, and the remainder is 0.64.
