We look at the division of 51237 by 47 
Let's see how many times 47 fits into 51237.

Step 1:
The number 47 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 47

Step 2:
47 goes into 51 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 47 from 51 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 47

On to step 3:
When dividing 42 by 47, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 42 to get 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 47

Let's proceed to step 4:
The number 47 fits into 423 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
The remainder is 0 after subtracting 423 from 423.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 47

Moving on to step 5:
When dividing 7 by 47, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 1090.0
Subtract 0 from 7 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 6:
When dividing 70 by 47, we get 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1090.1
Subtract 47 from 70 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.

Advancing to step 7:
47 goes into 230 4 times with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 1090.14
Deduct 188 from 230 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
47 can be fit into 420 8 times, resulting in a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 1090.148
The remainder is 44 after subtracting 376 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
47 can be fit into 440 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 1090.1489
The remainder is 17 after subtracting 423 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
When dividing 170 by 47, we get 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 1090.14893
Subtracting 141 from 170 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.

Advancing to step 11:
47 goes into 290 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 1090.148936
If we take 282 away from 290, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
47 goes into 80 1 times with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 1090.1489361
Subtracting 47 from 80 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 13:
The number 47 fits into 330 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 1090.14893617
Subtract 329 from 330 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.

The final result is 1090.14893617 with a remainder of 1e-09.
