We're dividing 42230451 by 440 
We want to figure out the number of times 42230451 can be divided by 440.

Let's proceed to step 1:
440 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 440

Let's proceed to step 2:
440 goes into 42 0 times with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 440

Step 3:
440 can be fit into 422 0 times, resulting in a remainder of 422.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 422, we end up with 422.
Grab the next digit (3) from the dividend, add it to 422, then carry on: 4223 / 440

Let's proceed to step 4:
If we divide 4223 by 440, we get 9 and a remainder of 263.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 3960 from 4223 to get 263.
Grab the next digit (0) from the dividend, add it to 263, then carry on: 2630 / 440

Going ahead to step 5:
When dividing 2630 by 440, we get 5 with a remainder of 430.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
If we take 2200 away from 2630, we end up with 430.
Include the next digit (4) from the dividend after 430, then repeat: 4304 / 440

Moving on to step 6:
440 can be fit into 4304 9 times, resulting in a remainder of 344.
Put 9 as the next digit of the answer. 
Result so far: 959.0
If we subtract 3960 from 4304, we get 344.
Append the next digit (5) from the dividend to 344 and continue with: 3445 / 440

Step 7:
When dividing 3445 by 440, we get 7 with a remainder of 365.
Use 7 as the next digit of our solution. 
Result so far: 9597.0
Subtracting 3080 from 3445 leaves us with 365.
Take the next digit (1) from the dividend and append it to 365, then repeat: 3651 / 440

On to step 8:
3651 divided by 440 is 8 with a remainder of 131.
The number 8 becomes the next digit in our result. 
Result so far: 95978.0
Subtracting 3520 from 3651 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 9:
440 can be fit into 1310 2 times, resulting in a remainder of 430.
Write down 2 as next digit of the result. 
Result so far: 95978.2
The remainder is 430 after subtracting 880 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 10:
4300 divided by 440 is 9 with a remainder of 340.
The next digit of our result is 9. 
Result so far: 95978.29
If we take 3960 away from 4300, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 11:
When dividing 3400 by 440, we get 7 with a remainder of 320.
Use 7 as the next digit of our solution. 
Result so far: 95978.297
The remainder is 320 after subtracting 3080 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 12:
440 goes into 3200 7 times with a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 95978.2977
Subtracting 3080 from 3200 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 95978.2977 with a remainder of 0.0012.
