87919717 divided by 51 
Our goal is to divide 87919717 by 51.

Let's proceed to step 1:
8 divided by 51 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 51

Let's proceed to step 2:
If we divide 87 by 51, we get 1 and a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 51 from 87 and we're left with 36.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 51

On to step 3:
369 divided by 51 is 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 357 from 369 and we're left with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 51

Going ahead to step 4:
The number 51 fits into 121 2 times, leaving a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
Deduct 102 from 121 and we're left with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 51

Moving on to step 5:
199 divided by 51 is 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 1723.0
The remainder is 46 after subtracting 153 from 199.
Include the next digit (7) from the dividend after 46, then repeat: 467 / 51

Advancing to step 6:
The number 51 fits into 467 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 17239.0
Deduct 459 from 467 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 51

On to step 7:
51 can be fit into 81 1 times, resulting in a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 172391.0
The remainder is 30 after subtracting 51 from 81.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 51

Let's proceed to step 8:
If we divide 307 by 51, we get 6 and a remainder of 1.
The next digit of our result is 6. 
Result so far: 1723916.0
Subtracting 306 from 307 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
When dividing 10 by 51, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1723916.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
The number 51 fits into 100 1 times, leaving a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 1723916.01
Subtract 51 from 100 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 11:
490 divided by 51 is 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 1723916.019
If we take 459 away from 490, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 12:
310 divided by 51 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 1723916.0196
If we take 306 away from 310, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
51 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1723916.0196
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
If we divide 400 by 51, we get 7 and a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 1723916.019607
Subtract 357 from 400 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 15:
51 goes into 430 8 times with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 1723916.0196078
The remainder is 22 after subtracting 408 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 16:
The number 51 fits into 220 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 1723916.01960784
Deduct 204 from 220 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 1723916.01960784 with a remainder of 1.6e-08.
