53669209 ÷ 154 
We want to figure out the number of times 53669209 can be divided by 154.

Step 1:
When dividing 5 by 154, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 154

Advancing to step 2:
The number 154 fits into 53 0 times, leaving a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 154

Let's proceed to step 3:
The number 154 fits into 536 3 times, leaving a remainder of 74.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 462 from 536 and we're left with 74.
Append the next digit (6) from the dividend to 74 and continue with: 746 / 154

Let's proceed to step 4:
746 divided by 154 is 4 with a remainder of 130.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 616 from 746 to get 130.
Take the next digit (9) from the dividend and append it to 130, then repeat: 1309 / 154

On to step 5:
154 goes into 1309 8 times with a remainder of 77.
Use 8 as the next digit of our solution. 
Result so far: 348.0
If we take 1232 away from 1309, we end up with 77.
Bring next digit (2) of the dividend behind the 77 and repeat the process: 772 / 154

Moving on to step 6:
772 divided by 154 is 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 3485.0
If we subtract 770 from 772, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 154

Let's proceed to step 7:
When dividing 20 by 154, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 34850.0
The remainder is 20 after subtracting 0 from 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 154

On to step 8:
154 can be fit into 209 1 times, resulting in a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 348501.0
If we take 154 away from 209, we end up 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 9:
154 can be fit into 550 3 times, resulting in a remainder of 88.
The next digit of our result is 3. 
Result so far: 348501.3
Subtracting 462 from 550 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 10:
If we divide 880 by 154, we get 5 and a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 348501.35
If we subtract 770 from 880, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 11:
154 can be fit into 1100 7 times, resulting in a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 348501.357
If we subtract 1078 from 1100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
154 can be fit into 220 1 times, resulting in a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 348501.3571
If we subtract 154 from 220, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 13:
The number 154 fits into 660 4 times, leaving a remainder of 44.
The next digit of our result is 4. 
Result so far: 348501.35714
Subtract 616 from 660 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
440 divided by 154 is 2 with a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 348501.357142
Subtract 308 from 440 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 15:
If we divide 1320 by 154, we get 8 and a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 348501.3571428
If we take 1232 away from 1320, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 16:
When dividing 880 by 154, we get 5 with a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 348501.35714285
Deduct 770 from 880 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

After the division, we end up with 348501.35714285 and a remainder of 1.1e-07.
