12437122 ÷ 254 
Let's see how many times 254 fits into 12437122.

On to step 1:
If we divide 1 by 254, we get 0 and 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.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 254

Moving on to step 2:
254 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 254

Going ahead to step 3:
If we divide 124 by 254, we get 0 and a remainder of 124.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 124, we get 124.
Grab the next digit (3) from the dividend, add it to 124, then carry on: 1243 / 254

On to step 4:
If we divide 1243 by 254, we get 4 and a remainder of 227.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 227 after subtracting 1016 from 1243.
Bring next digit (7) of the dividend behind the 227 and repeat the process: 2277 / 254

Advancing to step 5:
The number 254 fits into 2277 8 times, leaving a remainder of 245.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 2032 from 2277 to get 245.
Bring next digit (1) of the dividend behind the 245 and repeat the process: 2451 / 254

On to step 6:
254 can be fit into 2451 9 times, resulting in a remainder of 165.
The next digit of our result is 9. 
Result so far: 489.0
Deduct 2286 from 2451 and we're left with 165.
Append the next digit (2) from the dividend to 165 and continue with: 1652 / 254

Going ahead to step 7:
The number 254 fits into 1652 6 times, leaving a remainder of 128.
The next digit of our result is 6. 
Result so far: 4896.0
If we subtract 1524 from 1652, we get 128.
Bring next digit (2) of the dividend behind the 128 and repeat the process: 1282 / 254

Advancing to step 8:
If we divide 1282 by 254, we get 5 and a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 48965.0
If we subtract 1270 from 1282, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
The number 254 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 48965.0
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
254 can be fit into 1200 4 times, resulting in a remainder of 184.
Put 4 as the next digit of the answer. 
Result so far: 48965.04
The remainder is 184 after subtracting 1016 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 11:
When dividing 1840 by 254, we get 7 with a remainder of 62.
Write down 7 as next digit of the result. 
Result so far: 48965.047
Subtract 1778 from 1840 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
254 goes into 620 2 times with a remainder of 112.
The next digit of our result is 2. 
Result so far: 48965.0472
Subtracting 508 from 620 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 13:
If we divide 1120 by 254, we get 4 and a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 48965.04724
The remainder is 104 after subtracting 1016 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 14:
1040 divided by 254 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 48965.047244
Subtract 1016 from 1040 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 48965.047244 with a balance of 2.4e-06.
