Let's divide 64525453 by 789
We're looking to find how many times 789 goes into 64525453.

Advancing to step 1:
The number 789 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 789

On to step 2:
789 goes into 64 0 times with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 789

Let's proceed to step 3:
789 can be fit into 645 0 times, resulting in a remainder of 645.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 645 and we're left with 645.
Append the next digit (2) from the dividend to 645 and continue with: 6452 / 789

Moving on to step 4:
The number 789 fits into 6452 8 times, leaving a remainder of 140.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 6312 from 6452 leaves us with 140.
Bring next digit (5) of the dividend behind the 140 and repeat the process: 1405 / 789

Going ahead to step 5:
The number 789 fits into 1405 1 times, leaving a remainder of 616.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Deduct 789 from 1405 and we're left with 616.
Take the next digit (4) from the dividend and append it to 616, then repeat: 6164 / 789

On to step 6:
789 goes into 6164 7 times with a remainder of 641.
Write down 7 as next digit of the result. 
Result so far: 817.0
If we take 5523 away from 6164, we end up with 641.
Append the next digit (5) from the dividend to 641 and continue with: 6415 / 789

On to step 7:
789 can be fit into 6415 8 times, resulting in a remainder of 103.
Record the quotient 8 as the next digit in the result. 
Result so far: 8178.0
If we take 6312 away from 6415, we end up with 103.
Fetch the next digit (3) from the dividend, attach it to 103 and continue: 1033 / 789

Going ahead to step 8:
1033 divided by 789 is 1 with a remainder of 244.
Use 1 as the next digit of our solution. 
Result so far: 81781.0
If we subtract 789 from 1033, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 9:
When dividing 2440 by 789, we get 3 with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 81781.3
If we take 2367 away from 2440, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 10:
789 goes into 730 0 times with a remainder of 730.
Write down 0 as next digit of the result. 
Result so far: 81781.3
Deduct 0 from 730 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 11:
If we divide 7300 by 789, we get 9 and a remainder of 199.
Use 9 as the next digit of our solution. 
Result so far: 81781.309
Deduct 7101 from 7300 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 12:
The number 789 fits into 1990 2 times, leaving a remainder of 412.
The number 2 becomes the next digit in our result. 
Result so far: 81781.3092
Subtracting 1578 from 1990 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 13:
If we divide 4120 by 789, we get 5 and a remainder of 175.
The next digit of our result is 5. 
Result so far: 81781.30925
If we subtract 3945 from 4120, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 14:
If we divide 1750 by 789, we get 2 and a remainder of 172.
Write down 2 as next digit of the result. 
Result so far: 81781.309252
If we take 1578 away from 1750, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 15:
1720 divided by 789 is 2 with a remainder of 142.
Use 2 as the next digit of our solution. 
Result so far: 81781.3092522
If we subtract 1578 from 1720, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Our division results in 81781.3092522 with a remaining 1.42e-06.
