691091 divided by 51 
Our goal is to divide 691091 by 51.

Step 1:
When dividing 6 by 51, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 51

Moving on to step 2:
If we divide 69 by 51, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 51 from 69 leaves us with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 51

Going ahead to step 3:
181 divided by 51 is 3 with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 153 from 181 to get 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 51

Advancing to step 4:
If we divide 280 by 51, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
Deduct 255 from 280 and we're left with 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 51

On to step 5:
51 can be fit into 259 5 times, resulting in a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 1355.0
If we take 255 away from 259, we end up with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 51

Going ahead to step 6:
41 divided by 51 is 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 13550.0
Deduct 0 from 41 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
410 divided by 51 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 13550.8
If we subtract 408 from 410, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 51 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 13550.8
Deduct 0 from 20 and we're left with 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:
51 can be fit into 200 3 times, resulting in a remainder of 47.
The next digit of our result is 3. 
Result so far: 13550.803
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 10:
The number 51 fits into 470 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 13550.8039
Deduct 459 from 470 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
If we divide 110 by 51, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 13550.80392
Deduct 102 from 110 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
51 can be fit into 80 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 13550.803921
If we subtract 51 from 80, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 13:
290 divided by 51 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 13550.8039215
If we subtract 255 from 290, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
If we divide 350 by 51, we get 6 and a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 13550.80392156
If we subtract 306 from 350, we 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.

The quotient of the division is 13550.80392156, and the remainder is 4.4e-08.
