51357107 ÷ 195 
We're looking to find how many times 195 goes into 51357107.

Moving on to step 1:
5 divided by 195 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 195

Moving on to step 2:
The number 195 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 195

Step 3:
When dividing 513 by 195, we get 2 with a remainder of 123.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 390 from 513 and we're left with 123.
Grab the next digit (5) from the dividend, add it to 123, then carry on: 1235 / 195

Advancing to step 4:
The number 195 fits into 1235 6 times, leaving a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtracting 1170 from 1235 leaves us with 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 195

Let's proceed to step 5:
The number 195 fits into 657 3 times, leaving a remainder of 72.
The number 3 becomes the next digit in our result. 
Result so far: 263.0
Deduct 585 from 657 and we're left with 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 195

Moving on to step 6:
The number 195 fits into 721 3 times, leaving a remainder of 136.
The next digit of our result is 3. 
Result so far: 2633.0
Deduct 585 from 721 and we're left with 136.
Grab the next digit (0) from the dividend, add it to 136, then carry on: 1360 / 195

On to step 7:
195 can be fit into 1360 6 times, resulting in a remainder of 190.
Use 6 as the next digit of our solution. 
Result so far: 26336.0
If we subtract 1170 from 1360, we get 190.
Fetch the next digit (7) from the dividend, attach it to 190 and continue: 1907 / 195

Going ahead to step 8:
If we divide 1907 by 195, we get 9 and a remainder of 152.
Use 9 as the next digit of our solution. 
Result so far: 263369.0
If we take 1755 away from 1907, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 9:
195 can be fit into 1520 7 times, resulting in a remainder of 155.
Write down 7 as next digit of the result. 
Result so far: 263369.7
Subtracting 1365 from 1520 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 10:
If we divide 1550 by 195, we get 7 and a remainder of 185.
The next digit of our result is 7. 
Result so far: 263369.77
Subtract 1365 from 1550 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Our division results in 263369.77 with a remaining 0.185.
