87799397 divided by 51 
Let's see how many times 51 fits into 87799397.

Let's proceed to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 51

Advancing to step 2:
The number 51 fits into 87 1 times, leaving a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 51 away from 87, we end up with 36.
Fetch the next digit (7) from the dividend, attach it to 36 and continue: 367 / 51

On to step 3:
The number 51 fits into 367 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 17.0
If we take 357 away from 367, we end up with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 51

Going ahead to step 4:
51 can be fit into 109 2 times, resulting in a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
Deduct 102 from 109 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 51

Step 5:
When dividing 79 by 51, we get 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1721.0
The remainder is 28 after subtracting 51 from 79.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 51

On to step 6:
51 can be fit into 283 5 times, resulting in a remainder of 28.
The next digit of our result is 5. 
Result so far: 17215.0
Subtract 255 from 283 to get 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 51

Advancing to step 7:
If we divide 289 by 51, we get 5 and a remainder of 34.
The next digit of our result is 5. 
Result so far: 172155.0
If we subtract 255 from 289, we get 34.
Take the next digit (7) from the dividend and append it to 34, then repeat: 347 / 51

Moving on to step 8:
The number 51 fits into 347 6 times, leaving a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 1721556.0
If we subtract 306 from 347, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
When dividing 410 by 51, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1721556.8
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
If we divide 20 by 51, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1721556.8
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
If we divide 200 by 51, we get 3 and a remainder of 47.
The next digit of our result is 3. 
Result so far: 1721556.803
Deduct 153 from 200 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 12:
When dividing 470 by 51, we get 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 1721556.8039
Deduct 459 from 470 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 13:
When dividing 110 by 51, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1721556.80392
Deduct 102 from 110 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
51 goes into 80 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1721556.803921
Subtracting 51 from 80 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 15:
If we divide 290 by 51, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 1721556.8039215
Deduct 255 from 290 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 16:
The number 51 fits into 350 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 1721556.80392156
Subtracting 306 from 350 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 1721556.80392156 with a remainder of 4.4e-08.
