54128074 ÷ 103 
We want to figure out the number of times 54128074 can be divided by 103.

On to step 1:
5 divided by 103 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 103

On to step 2:
If we divide 54 by 103, we get 0 and a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 103

Advancing to step 3:
When dividing 541 by 103, we get 5 with a remainder of 26.
The next digit of our result is 5. 
Result so far: 5.0
If we take 515 away from 541, we end up with 26.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 103

Step 4:
103 can be fit into 262 2 times, resulting in a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Deduct 206 from 262 and we're left with 56.
Bring next digit (8) of the dividend behind the 56 and repeat the process: 568 / 103

Step 5:
103 goes into 568 5 times with a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 525.0
Deduct 515 from 568 and we're left with 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 103

Step 6:
If we divide 530 by 103, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 5255.0
Deduct 515 from 530 and we're left with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 103

On to step 7:
If we divide 157 by 103, we get 1 and a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 52551.0
The remainder is 54 after subtracting 103 from 157.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 103

Advancing to step 8:
When dividing 544 by 103, we get 5 with a remainder of 29.
The next digit of our result is 5. 
Result so far: 525515.0
Subtracting 515 from 544 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
When dividing 290 by 103, we get 2 with a remainder of 84.
The next digit of our result is 2. 
Result so far: 525515.2
If we take 206 away from 290, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 10:
When dividing 840 by 103, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 525515.28
If we subtract 824 from 840, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
When dividing 160 by 103, we get 1 with a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 525515.281
Subtracting 103 from 160 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 12:
The number 103 fits into 570 5 times, leaving a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 525515.2815
Subtracting 515 from 570 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 13:
The number 103 fits into 550 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 525515.28155
Deduct 515 from 550 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 525515.28155, and the remainder is 3.5e-05.
