Let's divide 40645243 by 125
We want to figure out the number of times 40645243 can be divided by 125.

Advancing to step 1:
4 divided by 125 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 125

Let's proceed to step 2:
If we divide 40 by 125, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 125

On to step 3:
125 goes into 406 3 times with a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 375 away from 406, we end up with 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 125

Advancing to step 4:
The number 125 fits into 314 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtracting 250 from 314 leaves us with 64.
Append the next digit (5) from the dividend to 64 and continue with: 645 / 125

On to step 5:
125 can be fit into 645 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 325.0
If we take 625 away from 645, we end up with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 125

Let's proceed to step 6:
125 can be fit into 202 1 times, resulting in a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 3251.0
Subtracting 125 from 202 leaves us with 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 125

Let's proceed to step 7:
125 goes into 774 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 32516.0
Subtract 750 from 774 to get 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 125

Let's proceed to step 8:
The number 125 fits into 243 1 times, leaving a remainder of 118.
The number 1 becomes the next digit in our result. 
Result so far: 325161.0
Subtract 125 from 243 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 9:
1180 divided by 125 is 9 with a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 325161.9
Subtract 1125 from 1180 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
If we divide 550 by 125, we get 4 and a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 325161.94
Subtracting 500 from 550 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
The number 125 fits into 500 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 325161.944
The remainder is 0 after subtracting 500 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 325161.944 and a remainder of 0.0.
