We divide 638351 by 51
Let's see how many times 51 fits into 638351.

Let's proceed to step 1:
51 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 51

Let's proceed to step 2:
63 divided by 51 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 12 after subtracting 51 from 63.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 51

Advancing to step 3:
The number 51 fits into 128 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 102 from 128 to get 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 51

On to step 4:
263 divided by 51 is 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtracting 255 from 263 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 51

Advancing to step 5:
The number 51 fits into 85 1 times, leaving a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 1251.0
Deduct 51 from 85 and we're left with 34.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 51

Going ahead to step 6:
51 goes into 341 6 times with a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 12516.0
If we take 306 away from 341, we end up with 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 7:
If we divide 350 by 51, we get 6 and a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 12516.6
Deduct 306 from 350 and we're left with 44.
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 8:
If we divide 440 by 51, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 12516.68
Subtracting 408 from 440 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
If we divide 320 by 51, we get 6 and a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 12516.686
The remainder is 14 after subtracting 306 from 320.
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 10:
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: 12516.6862
The remainder is 38 after subtracting 102 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
51 goes into 380 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 12516.68627
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 12:
51 can be fit into 230 4 times, resulting in a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 12516.686274
Subtracting 204 from 230 leaves us 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.

Moving on to step 13:
51 can be fit into 260 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12516.6862745
Subtracting 255 from 260 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
If we divide 50 by 51, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 12516.6862745
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 12516.6862745 with a balance of 5e-08.
