Let's divide 57245452 by 644
Let's see how many times 644 fits into 57245452.

Moving on to step 1:
The number 644 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 644

Step 2:
If we divide 57 by 644, we get 0 and a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 644

Advancing to step 3:
When dividing 572 by 644, we get 0 with a remainder of 572.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 572 after subtracting 0 from 572.
Append the next digit (4) from the dividend to 572 and continue with: 5724 / 644

Going ahead to step 4:
644 goes into 5724 8 times with a remainder of 572.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 5152 from 5724, we get 572.
Grab the next digit (5) from the dividend, add it to 572, then carry on: 5725 / 644

Let's proceed to step 5:
5725 divided by 644 is 8 with a remainder of 573.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Subtracting 5152 from 5725 leaves us with 573.
Grab the next digit (4) from the dividend, add it to 573, then carry on: 5734 / 644

Let's proceed to step 6:
644 goes into 5734 8 times with a remainder of 582.
Put 8 as the next digit of the answer. 
Result so far: 888.0
If we subtract 5152 from 5734, we get 582.
Fetch the next digit (5) from the dividend, attach it to 582 and continue: 5825 / 644

Going ahead to step 7:
644 goes into 5825 9 times with a remainder of 29.
The next digit of our result is 9. 
Result so far: 8889.0
Subtract 5796 from 5825 to get 29.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 644

Advancing to step 8:
The number 644 fits into 292 0 times, leaving a remainder of 292.
Use 0 as the next digit of our solution. 
Result so far: 88890.0
Deduct 0 from 292 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 9:
When dividing 2920 by 644, we get 4 with a remainder of 344.
Record the quotient 4 as the next digit in the result. 
Result so far: 88890.4
The remainder is 344 after subtracting 2576 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 10:
If we divide 3440 by 644, we get 5 and a remainder of 220.
Record the quotient 5 as the next digit in the result. 
Result so far: 88890.45
If we subtract 3220 from 3440, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 11:
2200 divided by 644 is 3 with a remainder of 268.
Write down 3 as next digit of the result. 
Result so far: 88890.453
Subtracting 1932 from 2200 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 12:
The number 644 fits into 2680 4 times, leaving a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 88890.4534
If we take 2576 away from 2680, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 13:
The number 644 fits into 1040 1 times, leaving a remainder of 396.
The number 1 becomes the next digit in our result. 
Result so far: 88890.45341
Deduct 644 from 1040 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 14:
644 goes into 3960 6 times with a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 88890.453416
Subtract 3864 from 3960 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 15:
960 divided by 644 is 1 with a remainder of 316.
Use 1 as the next digit of our solution. 
Result so far: 88890.4534161
The remainder is 316 after subtracting 644 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 16:
The number 644 fits into 3160 4 times, leaving a remainder of 584.
Record the quotient 4 as the next digit in the result. 
Result so far: 88890.45341614
Subtract 2576 from 3160 to 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.

In conclusion, the division gives 88890.45341614 with a balance of 5.84e-07.
