We look at the division of 580963 by 51 
We want to figure out the number of times 580963 can be divided by 51.

Step 1:
If we divide 5 by 51, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 51

Step 2:
The number 51 fits into 58 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 51 from 58 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 51

Let's proceed to step 3:
51 goes into 70 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 51 from 70 leaves us with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 51

Going ahead to step 4:
The number 51 fits into 199 3 times, leaving a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 113.0
If we take 153 away from 199, we end up with 46.
Take the next digit (6) from the dividend and append it to 46, then repeat: 466 / 51

Step 5:
If we divide 466 by 51, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 1139.0
Subtract 459 from 466 to get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 51

Let's proceed to step 6:
73 divided by 51 is 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 11391.0
Subtract 51 from 73 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
220 divided by 51 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 11391.4
The remainder is 16 after subtracting 204 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
When dividing 160 by 51, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 11391.43
If we take 153 away from 160, 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.

Moving on to step 9:
70 divided by 51 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 11391.431
Deduct 51 from 70 and we're left 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.

Step 10:
When dividing 190 by 51, we get 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 11391.4313
Subtract 153 from 190 to get 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 11:
When dividing 370 by 51, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 11391.43137
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.

Step 12:
The number 51 fits into 130 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 11391.431372
If we subtract 102 from 130, we get 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 13:
If we divide 280 by 51, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 11391.4313725
The remainder is 25 after subtracting 255 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 14:
If we divide 250 by 51, we get 4 and a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 11391.43137254
Subtracting 204 from 250 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 11391.43137254 and a remainder of 4.6e-08.
