771982 ÷ 51 
We want to figure out the number of times 771982 can be divided by 51.

On to step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 51

Going ahead to step 2:
51 can be fit into 77 1 times, resulting in a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 51 from 77, we get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 51

Advancing to step 3:
If we divide 261 by 51, we get 5 and a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 255 from 261 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 51

Going ahead to step 4:
If we divide 69 by 51, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 151.0
If we take 51 away from 69, we end up with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 51

Going ahead to step 5:
188 divided by 51 is 3 with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 1513.0
Subtract 153 from 188 to get 35.
Grab the next digit (2) from the dividend, add it to 35, then carry on: 352 / 51

Step 6:
If we divide 352 by 51, we get 6 and a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 15136.0
Subtracting 306 from 352 leaves us 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.

Going ahead to step 7:
The number 51 fits into 460 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 15136.9
Deduct 459 from 460 and we're left 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.

On to step 8:
10 divided by 51 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 15136.9
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.

Step 9:
The number 51 fits into 100 1 times, leaving a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 15136.901
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.

On to step 10:
The number 51 fits into 490 9 times, leaving a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 15136.9019
Subtract 459 from 490 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
51 can be fit into 310 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 15136.90196
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 12:
When dividing 40 by 51, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 15136.90196
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
The number 51 fits into 400 7 times, leaving a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 15136.9019607
Deduct 357 from 400 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 14:
51 can be fit into 430 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 15136.90196078
Deduct 408 from 430 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 15136.90196078, and the remainder is 2.2e-08.
