42397893 ÷ 952 
We want to figure out the number of times 42397893 can be divided by 952.

Going ahead to step 1:
The number 952 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 952

Step 2:
If we divide 42 by 952, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 952

Moving on to step 3:
952 can be fit into 423 0 times, resulting in a remainder of 423.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 423 leaves us with 423.
Grab the next digit (9) from the dividend, add it to 423, then carry on: 4239 / 952

Going ahead to step 4:
4239 divided by 952 is 4 with a remainder of 431.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 3808 from 4239 and we're left with 431.
Fetch the next digit (7) from the dividend, attach it to 431 and continue: 4317 / 952

Moving on to step 5:
4317 divided by 952 is 4 with a remainder of 509.
Use 4 as the next digit of our solution. 
Result so far: 44.0
The remainder is 509 after subtracting 3808 from 4317.
Bring next digit (8) of the dividend behind the 509 and repeat the process: 5098 / 952

Let's proceed to step 6:
If we divide 5098 by 952, we get 5 and a remainder of 338.
The number 5 becomes the next digit in our result. 
Result so far: 445.0
Subtracting 4760 from 5098 leaves us with 338.
Fetch the next digit (9) from the dividend, attach it to 338 and continue: 3389 / 952

Step 7:
3389 divided by 952 is 3 with a remainder of 533.
Use 3 as the next digit of our solution. 
Result so far: 4453.0
Subtract 2856 from 3389 to get 533.
Fetch the next digit (3) from the dividend, attach it to 533 and continue: 5333 / 952

Let's proceed to step 8:
If we divide 5333 by 952, we get 5 and a remainder of 573.
Write down 5 as next digit of the result. 
Result so far: 44535.0
If we subtract 4760 from 5333, we get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Step 9:
If we divide 5730 by 952, we get 6 and a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 44535.6
Subtracting 5712 from 5730 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
952 can be fit into 180 0 times, resulting in a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 44535.6
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
952 goes into 1800 1 times with a remainder of 848.
Record the quotient 1 as the next digit in the result. 
Result so far: 44535.601
If we take 952 away from 1800, we end up with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Advancing to step 12:
If we divide 8480 by 952, we get 8 and a remainder of 864.
The number 8 becomes the next digit in our result. 
Result so far: 44535.6018
Subtracting 7616 from 8480 leaves us with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Going ahead to step 13:
8640 divided by 952 is 9 with a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 44535.60189
The remainder is 72 after subtracting 8568 from 8640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
If we divide 720 by 952, we get 0 and a remainder of 720.
Put 0 as the next digit of the answer. 
Result so far: 44535.60189
Subtract 0 from 720 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 15:
7200 divided by 952 is 7 with a remainder of 536.
Record the quotient 7 as the next digit in the result. 
Result so far: 44535.6018907
If we subtract 6664 from 7200, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Moving on to step 16:
952 goes into 5360 5 times with a remainder of 600.
The next digit of our result is 5. 
Result so far: 44535.60189075
The remainder is 600 after subtracting 4760 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 44535.60189075 with a remainder of 6e-07.
