816691 ÷ 51 
Our goal is to divide 816691 by 51.

Advancing to step 1:
8 divided by 51 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 51

On to step 2:
51 goes into 81 1 times with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 51 away from 81, we end up with 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 51

Advancing to step 3:
51 goes into 306 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 306 away from 306, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 51

Step 4:
51 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 160.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 51

Moving on to step 5:
69 divided by 51 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1601.0
Deduct 51 from 69 and we're left with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 51

Going ahead to step 6:
181 divided by 51 is 3 with a remainder of 28.
The next digit of our result is 3. 
Result so far: 16013.0
The remainder is 28 after subtracting 153 from 181.
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 7:
The number 51 fits into 280 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 16013.5
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.

Going ahead to step 8:
When dividing 250 by 51, we get 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 16013.54
Subtract 204 from 250 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
51 can be fit into 460 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 16013.549
The remainder is 1 after subtracting 459 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
When dividing 10 by 51, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 16013.549
Subtracting 0 from 10 leaves us 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.

Advancing to step 11:
If we divide 100 by 51, we get 1 and a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 16013.54901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 12:
The number 51 fits into 490 9 times, leaving a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 16013.549019
If we take 459 away from 490, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 13:
51 goes into 310 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 16013.5490196
If we subtract 306 from 310, we get 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 14:
51 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 16013.5490196
Subtract 0 from 40 to 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.

In conclusion, the division gives 16013.5490196 with a balance of 4e-08.
