638833 divided by 51 
Our goal is to divide 638833 by 51.

Moving on to step 1:
51 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 51

Going ahead to step 2:
When dividing 63 by 51, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 51 from 63 to get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 51

Advancing to step 3:
51 goes into 128 2 times with a remainder of 26.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 102 from 128 to get 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 51

Moving on to step 4:
When dividing 268 by 51, we get 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 125.0
If we subtract 255 from 268, we get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 51

On to step 5:
51 can be fit into 133 2 times, resulting in a remainder of 31.
The next digit of our result is 2. 
Result so far: 1252.0
If we subtract 102 from 133, we get 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 51

On to step 6:
51 can be fit into 313 6 times, resulting in a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 12526.0
If we take 306 away from 313, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
The number 51 fits into 70 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 12526.1
If we take 51 away from 70, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
190 divided by 51 is 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 12526.13
Deduct 153 from 190 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
51 goes into 370 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 12526.137
Subtract 357 from 370 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
51 goes into 130 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 12526.1372
Subtracting 102 from 130 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
The number 51 fits into 280 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 12526.13725
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.

Moving on to step 12:
51 can be fit into 250 4 times, resulting in a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 12526.137254
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.

On to step 13:
If we divide 460 by 51, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 12526.1372549
If we subtract 459 from 460, we get 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 14:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 12526.1372549
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.

After the division, we end up with 12526.1372549 and a remainder of 1e-08.
