We divide 767979 by 51
We want to figure out the number of times 767979 can be divided by 51.

Advancing to step 1:
51 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 51

Going ahead to step 2:
The number 51 fits into 76 1 times, leaving a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 25 after subtracting 51 from 76.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 51

Moving on to step 3:
If we divide 257 by 51, we get 5 and a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 255 from 257, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 51

On to step 4:
When dividing 29 by 51, we get 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 150.0
If we subtract 0 from 29, we get 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 51

On to step 5:
If we divide 297 by 51, we get 5 and a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 1505.0
Deduct 255 from 297 and we're left with 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 51

Let's proceed to step 6:
51 can be fit into 429 8 times, resulting in a remainder of 21.
The next digit of our result is 8. 
Result so far: 15058.0
Deduct 408 from 429 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
210 divided by 51 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 15058.4
Subtracting 204 from 210 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
If we divide 60 by 51, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 15058.41
Subtracting 51 from 60 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
51 goes into 90 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 15058.411
If we subtract 51 from 90, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 15058.411 with a remaining 0.0039.
