We divide 12497170 by 278
We want to figure out the number of times 12497170 can be divided by 278.

On to step 1:
278 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 278

On to step 2:
The number 278 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 278

On to step 3:
If we divide 124 by 278, 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 take 0 away from 124, we end up with 124.
Include the next digit (9) from the dividend after 124, then repeat: 1249 / 278

Let's proceed to step 4:
If we divide 1249 by 278, we get 4 and a remainder of 137.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 1112 from 1249 leaves us with 137.
Bring next digit (7) of the dividend behind the 137 and repeat the process: 1377 / 278

Step 5:
If we divide 1377 by 278, we get 4 and a remainder of 265.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 1112 from 1377, we get 265.
Include the next digit (1) from the dividend after 265, then repeat: 2651 / 278

Step 6:
278 goes into 2651 9 times with a remainder of 149.
Write down 9 as next digit of the result. 
Result so far: 449.0
Subtract 2502 from 2651 to get 149.
Include the next digit (7) from the dividend after 149, then repeat: 1497 / 278

Going ahead to step 7:
278 can be fit into 1497 5 times, resulting in a remainder of 107.
Record the quotient 5 as the next digit in the result. 
Result so far: 4495.0
Subtract 1390 from 1497 to get 107.
Include the next digit (0) from the dividend after 107, then repeat: 1070 / 278

On to step 8:
The number 278 fits into 1070 3 times, leaving a remainder of 236.
Record the quotient 3 as the next digit in the result. 
Result so far: 44953.0
Deduct 834 from 1070 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 9:
2360 divided by 278 is 8 with a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 44953.8
The remainder is 136 after subtracting 2224 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
278 can be fit into 1360 4 times, resulting in a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 44953.84
The remainder is 248 after subtracting 1112 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 11:
278 can be fit into 2480 8 times, resulting in a remainder of 256.
The next digit of our result is 8. 
Result so far: 44953.848
Deduct 2224 from 2480 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 12:
When dividing 2560 by 278, we get 9 with a remainder of 58.
The next digit of our result is 9. 
Result so far: 44953.8489
Subtract 2502 from 2560 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
When dividing 580 by 278, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 44953.84892
If we take 556 away from 580, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
240 divided by 278 is 0 with a remainder of 240.
The next digit of our result is 0. 
Result so far: 44953.84892
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 15:
278 goes into 2400 8 times with a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 44953.8489208
Subtract 2224 from 2400 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 16:
1760 divided by 278 is 6 with a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 44953.84892086
Subtracting 1668 from 1760 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

In conclusion, the division gives 44953.84892086 with a balance of 9.2e-08.
