26186636 ÷ 103 
We want to divide 26186636 by 103.

On to step 1:
103 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 103

Step 2:
When dividing 26 by 103, we get 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 103

Advancing to step 3:
261 divided by 103 is 2 with a remainder of 55.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 206 from 261, we get 55.
Grab the next digit (8) from the dividend, add it to 55, then carry on: 558 / 103

Step 4:
103 goes into 558 5 times with a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 43 after subtracting 515 from 558.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 103

On to step 5:
436 divided by 103 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 254.0
If we subtract 412 from 436, we get 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 103

Advancing to step 6:
If we divide 246 by 103, we get 2 and a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 2542.0
If we take 206 away from 246, we end up with 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 103

Advancing to step 7:
403 divided by 103 is 3 with a remainder of 94.
Put 3 as the next digit of the answer. 
Result so far: 25423.0
If we subtract 309 from 403, we get 94.
Bring next digit (6) of the dividend behind the 94 and repeat the process: 946 / 103

On to step 8:
946 divided by 103 is 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 254239.0
The remainder is 19 after subtracting 927 from 946.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
103 goes into 190 1 times with a remainder of 87.
Write down 1 as next digit of the result. 
Result so far: 254239.1
Deduct 103 from 190 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 10:
The number 103 fits into 870 8 times, leaving a remainder of 46.
The next digit of our result is 8. 
Result so far: 254239.18
The remainder is 46 after subtracting 824 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
103 can be fit into 460 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 254239.184
If we take 412 away from 460, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
The number 103 fits into 480 4 times, leaving a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 254239.1844
The remainder is 68 after subtracting 412 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 254239.1844, with a leftover of 0.00068.
