We're dividing 77098146 by 51 
Our goal is to divide 77098146 by 51.

Step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 51

Let's proceed to step 2:
When dividing 77 by 51, we get 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 51 from 77 leaves us with 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 51

Moving on to step 3:
51 goes into 260 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 255 from 260 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 51

Step 4:
If we divide 59 by 51, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 151.0
If we take 51 away from 59, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 51

Step 5:
The number 51 fits into 88 1 times, leaving a remainder of 37.
The next digit of our result is 1. 
Result so far: 1511.0
If we take 51 away from 88, we end up with 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 51

Advancing to step 6:
371 divided by 51 is 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 15117.0
Subtracting 357 from 371 leaves us with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 51

On to step 7:
144 divided by 51 is 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 151172.0
Subtract 102 from 144 to get 42.
Grab the next digit (6) from the dividend, add it to 42, then carry on: 426 / 51

Advancing to step 8:
426 divided by 51 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 1511728.0
Subtracting 408 from 426 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
When dividing 180 by 51, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 1511728.3
Subtracting 153 from 180 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 10:
51 goes into 270 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1511728.35
The remainder is 15 after subtracting 255 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
When dividing 150 by 51, we get 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 1511728.352
If we subtract 102 from 150, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
If we divide 480 by 51, we get 9 and a remainder of 21.
The next digit of our result is 9. 
Result so far: 1511728.3529
If we subtract 459 from 480, we get 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 13:
When dividing 210 by 51, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1511728.35294
The remainder is 6 after subtracting 204 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
51 goes into 60 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1511728.352941
If we subtract 51 from 60, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 15:
51 can be fit into 90 1 times, resulting in a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 1511728.3529411
Deduct 51 from 90 and we're left with 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 1511728.3529411 with a remaining 3.9e-07.
