We look at the division of 42439516 by 195 
We're looking to find how many times 195 goes into 42439516.

Moving on to step 1:
The number 195 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 195

Going ahead to step 2:
195 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 195

On to step 3:
195 goes into 424 2 times with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 390 from 424 to get 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 195

Going ahead to step 4:
When dividing 343 by 195, we get 1 with a remainder of 148.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 148 after subtracting 195 from 343.
Append the next digit (9) from the dividend to 148 and continue with: 1489 / 195

Moving on to step 5:
195 can be fit into 1489 7 times, resulting in a remainder of 124.
Use 7 as the next digit of our solution. 
Result so far: 217.0
The remainder is 124 after subtracting 1365 from 1489.
Append the next digit (5) from the dividend to 124 and continue with: 1245 / 195

Let's proceed to step 6:
195 can be fit into 1245 6 times, resulting in a remainder of 75.
The number 6 becomes the next digit in our result. 
Result so far: 2176.0
Deduct 1170 from 1245 and we're left with 75.
Append the next digit (1) from the dividend to 75 and continue with: 751 / 195

Moving on to step 7:
195 can be fit into 751 3 times, resulting in a remainder of 166.
Put 3 as the next digit of the answer. 
Result so far: 21763.0
Subtract 585 from 751 to get 166.
Fetch the next digit (6) from the dividend, attach it to 166 and continue: 1666 / 195

Moving on to step 8:
The number 195 fits into 1666 8 times, leaving a remainder of 106.
Write down 8 as next digit of the result. 
Result so far: 217638.0
If we take 1560 away from 1666, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 9:
1060 divided by 195 is 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 217638.5
Subtracting 975 from 1060 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
195 goes into 850 4 times with a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 217638.54
If we take 780 away from 850, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
The number 195 fits into 700 3 times, leaving a remainder of 115.
Record the quotient 3 as the next digit in the result. 
Result so far: 217638.543
The remainder is 115 after subtracting 585 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 12:
If we divide 1150 by 195, we get 5 and a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 217638.5435
Subtracting 975 from 1150 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 13:
195 can be fit into 1750 8 times, resulting in a remainder of 190.
Use 8 as the next digit of our solution. 
Result so far: 217638.54358
If we subtract 1560 from 1750, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 14:
1900 divided by 195 is 9 with a remainder of 145.
Record the quotient 9 as the next digit in the result. 
Result so far: 217638.543589
If we subtract 1755 from 1900, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 15:
195 goes into 1450 7 times with a remainder of 85.
The next digit of our result is 7. 
Result so far: 217638.5435897
If we subtract 1365 from 1450, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 16:
195 goes into 850 4 times with a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 217638.54358974
The remainder is 70 after subtracting 780 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 217638.54358974 with a remaining 7e-08.
