Let's divide 51978047 by 51
We want to figure out the number of times 51978047 can be divided by 51.

On to step 1:
The number 51 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 51

Going ahead to step 2:
51 can be fit into 51 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 51 from 51 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 51

On to step 3:
When dividing 9 by 51, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 9, we end up with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 51

Step 4:
97 divided by 51 is 1 with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Deduct 51 from 97 and we're left with 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 51

Going ahead to step 5:
When dividing 468 by 51, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 1019.0
If we subtract 459 from 468, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 51

Step 6:
51 goes into 90 1 times with a remainder of 39.
The next digit of our result is 1. 
Result so far: 10191.0
Deduct 51 from 90 and we're left with 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 51

On to step 7:
51 can be fit into 394 7 times, resulting in a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 101917.0
Deduct 357 from 394 and we're left with 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 51

Moving on to step 8:
If we divide 377 by 51, we get 7 and a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 1019177.0
Subtract 357 from 377 to 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.

Going ahead to step 9:
If we divide 200 by 51, we get 3 and a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 1019177.3
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.

On to step 10:
51 can be fit into 470 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1019177.39
Subtract 459 from 470 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
When dividing 110 by 51, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 1019177.392
Subtract 102 from 110 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
The number 51 fits into 80 1 times, leaving a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1019177.3921
If we take 51 away from 80, we end up 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.

Moving on to step 13:
290 divided by 51 is 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1019177.39215
The remainder is 35 after subtracting 255 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
The number 51 fits into 350 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 1019177.392156
Subtract 306 from 350 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 15:
440 divided by 51 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 1019177.3921568
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 16:
If we divide 320 by 51, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 1019177.39215686
The remainder is 14 after subtracting 306 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 1019177.39215686 with a remaining 1.4e-08.
