74099021 ÷ 55 
We want to figure out the number of times 74099021 can be divided by 55.

On to step 1:
55 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 55

Step 2:
74 divided by 55 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 55 from 74 and we're left with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 55

Let's proceed to step 3:
If we divide 190 by 55, we get 3 and a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 165 away from 190, we end up with 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 55

Advancing to step 4:
If we divide 259 by 55, we get 4 and a remainder of 39.
The next digit of our result is 4. 
Result so far: 134.0
If we subtract 220 from 259, we get 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 55

Advancing to step 5:
55 can be fit into 399 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 1347.0
If we subtract 385 from 399, we get 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 55

Let's proceed to step 6:
The number 55 fits into 140 2 times, leaving a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 13472.0
Subtracting 110 from 140 leaves us with 30.
Append the next digit (2) from the dividend to 30 and continue with: 302 / 55

Advancing to step 7:
55 can be fit into 302 5 times, resulting in a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 134725.0
Subtracting 275 from 302 leaves us with 27.
Take the next digit (1) from the dividend and append it to 27, then repeat: 271 / 55

On to step 8:
55 goes into 271 4 times with a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 1347254.0
If we take 220 away from 271, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
55 goes into 510 9 times with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 1347254.9
Subtracting 495 from 510 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
55 goes into 150 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 1347254.92
Deduct 110 from 150 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
When dividing 400 by 55, we get 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 1347254.927
If we take 385 away from 400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
The number 55 fits into 150 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 1347254.9272
If we take 110 away from 150, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
55 can be fit into 400 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 1347254.92727
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 14:
55 can be fit into 150 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 1347254.927272
If we subtract 110 from 150, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
If we divide 400 by 55, we get 7 and a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 1347254.9272727
If we take 385 away from 400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 16:
55 goes into 150 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 1347254.92727272
If we subtract 110 from 150, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 1347254.92727272 with a remainder of 4e-08.
