693975 divided by 51 
We want to figure out the number of times 693975 can be divided by 51.

Let's proceed to step 1:
6 divided by 51 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 51

Advancing to step 2:
51 can be fit into 69 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 18 after subtracting 51 from 69.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 51

Step 3:
If we divide 183 by 51, we get 3 and a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 153 from 183, we get 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 51

Advancing to step 4:
If we divide 309 by 51, we get 6 and a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
If we subtract 306 from 309, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 51

Let's proceed to step 5:
37 divided by 51 is 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 1360.0
If we take 0 away from 37, we end up with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 51

Going ahead to step 6:
51 goes into 375 7 times with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 13607.0
Subtracting 357 from 375 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.

Going ahead to step 7:
When dividing 180 by 51, we get 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 13607.3
The remainder is 27 after subtracting 153 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
If we divide 270 by 51, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 13607.35
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 9:
If we divide 150 by 51, we get 2 and a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 13607.352
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.

Going ahead to step 10:
If we divide 480 by 51, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 13607.3529
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.

Let's proceed to step 11:
When dividing 210 by 51, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 13607.35294
Deduct 204 from 210 and we're left 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.

Step 12:
51 goes into 60 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 13607.352941
The remainder is 9 after subtracting 51 from 60.
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 13:
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: 13607.3529411
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.

After the division, we end up with 13607.3529411 and a remainder of 3.9e-07.
