87394432 divided by 51 
Let's see how many times 51 fits into 87394432.

Going ahead to step 1:
If we divide 8 by 51, we get 0 and 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.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 51

Going ahead to step 2:
51 goes into 87 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 51 from 87, we get 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 51

Step 3:
The number 51 fits into 363 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 357 from 363, we get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 51

Moving on to step 4:
51 can be fit into 69 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 171.0
Subtract 51 from 69 to get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 51

Moving on to step 5:
51 can be fit into 184 3 times, resulting in a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 1713.0
If we subtract 153 from 184, we get 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 51

Step 6:
51 goes into 314 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 17136.0
Subtract 306 from 314 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 51

Advancing to step 7:
83 divided by 51 is 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 171361.0
If we take 51 away from 83, we end up with 32.
Include the next digit (2) from the dividend after 32, then repeat: 322 / 51

Step 8:
If we divide 322 by 51, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 1713616.0
If we take 306 away from 322, we end up 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.

Step 9:
The number 51 fits into 160 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 1713616.3
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
The number 51 fits into 70 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 1713616.31
Deduct 51 from 70 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 11:
51 goes into 190 3 times with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 1713616.313
Subtract 153 from 190 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 12:
When dividing 370 by 51, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 1713616.3137
Subtract 357 from 370 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 13:
130 divided by 51 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 1713616.31372
If we subtract 102 from 130, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
280 divided by 51 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1713616.313725
Subtract 255 from 280 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 15:
The number 51 fits into 250 4 times, leaving a remainder of 46.
The next digit of our result is 4. 
Result so far: 1713616.3137254
Deduct 204 from 250 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 16:
460 divided by 51 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1713616.31372549
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 1713616.31372549 with a balance of 1e-09.
