Let's divide 64336423 by 870
We want to figure out the number of times 64336423 can be divided by 870.

Advancing to step 1:
870 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 870

Advancing to step 2:
If we divide 64 by 870, we get 0 and a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 870

Step 3:
643 divided by 870 is 0 with a remainder of 643.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 643 leaves us with 643.
Bring next digit (3) of the dividend behind the 643 and repeat the process: 6433 / 870

Advancing to step 4:
870 can be fit into 6433 7 times, resulting in a remainder of 343.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 6090 from 6433, we get 343.
Append the next digit (6) from the dividend to 343 and continue with: 3436 / 870

Let's proceed to step 5:
When dividing 3436 by 870, we get 3 with a remainder of 826.
The next digit of our result is 3. 
Result so far: 73.0
Subtract 2610 from 3436 to get 826.
Grab the next digit (4) from the dividend, add it to 826, then carry on: 8264 / 870

Moving on to step 6:
The number 870 fits into 8264 9 times, leaving a remainder of 434.
Put 9 as the next digit of the answer. 
Result so far: 739.0
If we subtract 7830 from 8264, we get 434.
Take the next digit (2) from the dividend and append it to 434, then repeat: 4342 / 870

On to step 7:
The number 870 fits into 4342 4 times, leaving a remainder of 862.
The next digit of our result is 4. 
Result so far: 7394.0
If we take 3480 away from 4342, we end up with 862.
Include the next digit (3) from the dividend after 862, then repeat: 8623 / 870

Advancing to step 8:
The number 870 fits into 8623 9 times, leaving a remainder of 793.
The next digit of our result is 9. 
Result so far: 73949.0
The remainder is 793 after subtracting 7830 from 8623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

On to step 9:
The number 870 fits into 7930 9 times, leaving a remainder of 100.
Write down 9 as next digit of the result. 
Result so far: 73949.9
Deduct 7830 from 7930 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 10:
870 goes into 1000 1 times with a remainder of 130.
Use 1 as the next digit of our solution. 
Result so far: 73949.91
Subtracting 870 from 1000 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 11:
The number 870 fits into 1300 1 times, leaving a remainder of 430.
The number 1 becomes the next digit in our result. 
Result so far: 73949.911
Subtracting 870 from 1300 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

In conclusion, the division gives 73949.911 with a balance of 0.043.
