We're dividing 673943 by 51 
We want to divide 673943 by 51.

On to step 1:
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: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 51

Advancing to step 2:
When dividing 67 by 51, we get 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 16 after subtracting 51 from 67.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 51

Moving on to step 3:
51 goes into 163 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 153 from 163, we get 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 51

Step 4:
51 goes into 109 2 times with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 132.0
Subtract 102 from 109 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 51

Moving on to step 5:
74 divided by 51 is 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1321.0
The remainder is 23 after subtracting 51 from 74.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 51

Advancing to step 6:
When dividing 233 by 51, we get 4 with a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 13214.0
Subtracting 204 from 233 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
290 divided by 51 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 13214.5
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.

Let's proceed to step 8:
The number 51 fits into 350 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 13214.56
The remainder is 44 after subtracting 306 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
The number 51 fits into 440 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 13214.568
Subtract 408 from 440 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
320 divided by 51 is 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 13214.5686
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
If we divide 140 by 51, we get 2 and a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 13214.56862
Deduct 102 from 140 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
51 goes into 380 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 13214.568627
Subtract 357 from 380 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
If we divide 230 by 51, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 13214.5686274
If we take 204 away from 230, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
The number 51 fits into 260 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 13214.56862745
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 13214.56862745 and a remainder of 5e-09.
