We look at the division of 5912506 by 51 
We want to divide 5912506 by 51.

On to step 1:
When dividing 5 by 51, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 51

On to step 2:
The number 51 fits into 59 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 51 from 59 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 51

Going ahead to step 3:
When dividing 81 by 51, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 51 from 81 and we're left with 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 51

Step 4:
If we divide 302 by 51, we get 5 and a remainder of 47.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
If we take 255 away from 302, we end up with 47.
Include the next digit (5) from the dividend after 47, then repeat: 475 / 51

Moving on to step 5:
51 goes into 475 9 times with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 1159.0
If we subtract 459 from 475, we get 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 51

Let's proceed to step 6:
The number 51 fits into 160 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 11593.0
If we take 153 away from 160, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 51

Let's proceed to step 7:
76 divided by 51 is 1 with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 115931.0
Subtract 51 from 76 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.

Going ahead to step 8:
When dividing 250 by 51, we get 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 115931.4
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.

Step 9:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 115931.49
Subtract 459 from 460 to 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.

Going ahead to step 10:
If we divide 10 by 51, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 115931.49
Subtracting 0 from 10 leaves us 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.

On to step 11:
51 goes into 100 1 times with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 115931.4901
Subtract 51 from 100 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 12:
When dividing 490 by 51, we get 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 115931.49019
The remainder is 31 after subtracting 459 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 13:
When dividing 310 by 51, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 115931.490196
Deduct 306 from 310 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
51 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 115931.490196
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
The number 51 fits into 400 7 times, leaving a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 115931.49019607
If we subtract 357 from 400, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final outcome is 115931.49019607, with a leftover of 4.3e-08.
