Let's divide 51151258 by 254
We're looking to find how many times 254 goes into 51151258.

Step 1:
The number 254 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 254

On to step 2:
When dividing 51 by 254, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (1) of the dividend behind the 51 and repeat the process: 511 / 254

Let's proceed to step 3:
511 divided by 254 is 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 508 from 511 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 254

Going ahead to step 4:
The number 254 fits into 35 0 times, leaving a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 35, we end up with 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 254

Step 5:
The number 254 fits into 351 1 times, leaving a remainder of 97.
Record the quotient 1 as the next digit in the result. 
Result so far: 201.0
Deduct 254 from 351 and we're left with 97.
Append the next digit (2) from the dividend to 97 and continue with: 972 / 254

Step 6:
254 goes into 972 3 times with a remainder of 210.
The number 3 becomes the next digit in our result. 
Result so far: 2013.0
Subtracting 762 from 972 leaves us with 210.
Grab the next digit (5) from the dividend, add it to 210, then carry on: 2105 / 254

Moving on to step 7:
2105 divided by 254 is 8 with a remainder of 73.
Write down 8 as next digit of the result. 
Result so far: 20138.0
Subtract 2032 from 2105 to get 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 254

Advancing to step 8:
254 can be fit into 738 2 times, resulting in a remainder of 230.
Put 2 as the next digit of the answer. 
Result so far: 201382.0
The remainder is 230 after subtracting 508 from 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 9:
If we divide 2300 by 254, we get 9 and a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 201382.9
If we take 2286 away from 2300, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
When dividing 140 by 254, we get 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 201382.9
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 11:
254 can be fit into 1400 5 times, resulting in a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 201382.905
If we subtract 1270 from 1400, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 12:
If we divide 1300 by 254, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 201382.9055
Deduct 1270 from 1300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 201382.9055 with a remainder of 0.0003.
