We're dividing 123760 by 51 
Our goal is to divide 123760 by 51.

Step 1:
When dividing 1 by 51, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 51

Going ahead to step 2:
The number 51 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 51

Going ahead to step 3:
123 divided by 51 is 2 with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 21 after subtracting 102 from 123.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 51

Step 4:
When dividing 217 by 51, we get 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Deduct 204 from 217 and we're left with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 51

On to step 5:
If we divide 136 by 51, we get 2 and a remainder of 34.
The next digit of our result is 2. 
Result so far: 242.0
Deduct 102 from 136 and we're left with 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 51

Going ahead to step 6:
When dividing 340 by 51, we get 6 with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 2426.0
The remainder is 34 after subtracting 306 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
If we divide 340 by 51, we get 6 and a remainder of 34.
The next digit of our result is 6. 
Result so far: 2426.6
Deduct 306 from 340 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
51 can be fit into 340 6 times, resulting in a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 2426.66
Subtract 306 from 340 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 2426.66 with a remaining 0.034.
