51646641 ÷ 195 
We want to figure out the number of times 51646641 can be divided by 195.

Going ahead to step 1:
When dividing 5 by 195, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 195

Going ahead to step 2:
51 divided by 195 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 195

On to step 3:
If we divide 516 by 195, we get 2 and a remainder of 126.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 390 from 516 and we're left with 126.
Bring next digit (4) of the dividend behind the 126 and repeat the process: 1264 / 195

Advancing to step 4:
When dividing 1264 by 195, we get 6 with a remainder of 94.
The next digit of our result is 6. 
Result so far: 26.0
If we take 1170 away from 1264, we end up with 94.
Bring next digit (6) of the dividend behind the 94 and repeat the process: 946 / 195

Advancing to step 5:
If we divide 946 by 195, we get 4 and a remainder of 166.
The number 4 becomes the next digit in our result. 
Result so far: 264.0
The remainder is 166 after subtracting 780 from 946.
Include the next digit (6) from the dividend after 166, then repeat: 1666 / 195

On to step 6:
195 goes into 1666 8 times with a remainder of 106.
Put 8 as the next digit of the answer. 
Result so far: 2648.0
Subtracting 1560 from 1666 leaves us with 106.
Fetch the next digit (4) from the dividend, attach it to 106 and continue: 1064 / 195

Advancing to step 7:
When dividing 1064 by 195, we get 5 with a remainder of 89.
Record the quotient 5 as the next digit in the result. 
Result so far: 26485.0
Deduct 975 from 1064 and we're left with 89.
Grab the next digit (1) from the dividend, add it to 89, then carry on: 891 / 195

Advancing to step 8:
891 divided by 195 is 4 with a remainder of 111.
Write down 4 as next digit of the result. 
Result so far: 264854.0
If we take 780 away from 891, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 9:
1110 divided by 195 is 5 with a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 264854.5
The remainder is 135 after subtracting 975 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 10:
When dividing 1350 by 195, we get 6 with a remainder of 180.
The next digit of our result is 6. 
Result so far: 264854.56
Subtract 1170 from 1350 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:
195 can be fit into 1800 9 times, resulting in a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 264854.569
Deduct 1755 from 1800 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 12:
450 divided by 195 is 2 with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 264854.5692
If we take 390 away from 450, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
195 goes into 600 3 times with a remainder of 15.
The next digit of our result is 3. 
Result so far: 264854.56923
The remainder is 15 after subtracting 585 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
195 can be fit into 150 0 times, resulting in a remainder of 150.
The next digit of our result is 0. 
Result so far: 264854.56923
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 15:
195 goes into 1500 7 times with a remainder of 135.
Use 7 as the next digit of our solution. 
Result so far: 264854.5692307
Deduct 1365 from 1500 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 16:
If we divide 1350 by 195, we get 6 and a remainder of 180.
Write down 6 as next digit of the result. 
Result so far: 264854.56923076
Subtract 1170 from 1350 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.

The final result is 264854.56923076 with a remainder of 1.8e-07.
