74021455 ÷ 548 
We want to figure out the number of times 74021455 can be divided by 548.

Step 1:
When dividing 7 by 548, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 548

Advancing to step 2:
When dividing 74 by 548, we get 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Include the next digit (0) from the dividend after 74, then repeat: 740 / 548

Going ahead to step 3:
If we divide 740 by 548, we get 1 and a remainder of 192.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 548 from 740, we get 192.
Append the next digit (2) from the dividend to 192 and continue with: 1922 / 548

Moving on to step 4:
548 can be fit into 1922 3 times, resulting in a remainder of 278.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 278 after subtracting 1644 from 1922.
Bring next digit (1) of the dividend behind the 278 and repeat the process: 2781 / 548

Going ahead to step 5:
When dividing 2781 by 548, we get 5 with a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
Deduct 2740 from 2781 and we're left with 41.
Fetch the next digit (4) from the dividend, attach it to 41 and continue: 414 / 548

Let's proceed to step 6:
When dividing 414 by 548, we get 0 with a remainder of 414.
The next digit of our result is 0. 
Result so far: 1350.0
Subtracting 0 from 414 leaves us with 414.
Include the next digit (5) from the dividend after 414, then repeat: 4145 / 548

Going ahead to step 7:
If we divide 4145 by 548, we get 7 and a remainder of 309.
Put 7 as the next digit of the answer. 
Result so far: 13507.0
Subtract 3836 from 4145 to get 309.
Append the next digit (5) from the dividend to 309 and continue with: 3095 / 548

Let's proceed to step 8:
548 goes into 3095 5 times with a remainder of 355.
The next digit of our result is 5. 
Result so far: 135075.0
If we take 2740 away from 3095, we end up with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

On to step 9:
548 goes into 3550 6 times with a remainder of 262.
The number 6 becomes the next digit in our result. 
Result so far: 135075.6
If we subtract 3288 from 3550, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 10:
If we divide 2620 by 548, we get 4 and a remainder of 428.
Use 4 as the next digit of our solution. 
Result so far: 135075.64
Subtracting 2192 from 2620 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 11:
The number 548 fits into 4280 7 times, leaving a remainder of 444.
Use 7 as the next digit of our solution. 
Result so far: 135075.647
If we subtract 3836 from 4280, we get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 12:
4440 divided by 548 is 8 with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 135075.6478
Deduct 4384 from 4440 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
548 goes into 560 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 135075.64781
Subtracting 548 from 560 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
120 divided by 548 is 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 135075.64781
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 15:
1200 divided by 548 is 2 with a remainder of 104.
The next digit of our result is 2. 
Result so far: 135075.6478102
Deduct 1096 from 1200 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 16:
If we divide 1040 by 548, we get 1 and a remainder of 492.
Use 1 as the next digit of our solution. 
Result so far: 135075.64781021
If we subtract 548 from 1040, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

The final result is 135075.64781021 with a remainder of 4.92e-07.
