28641740 ÷ 154 
We want to figure out the number of times 28641740 can be divided by 154.

Step 1:
2 divided by 154 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 154

Step 2:
28 divided by 154 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 154

Moving on to step 3:
The number 154 fits into 286 1 times, leaving a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 154 from 286 leaves us with 132.
Bring next digit (4) of the dividend behind the 132 and repeat the process: 1324 / 154

Going ahead to step 4:
1324 divided by 154 is 8 with a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 1232 from 1324 and we're left with 92.
Fetch the next digit (1) from the dividend, attach it to 92 and continue: 921 / 154

Let's proceed to step 5:
921 divided by 154 is 5 with a remainder of 151.
The next digit of our result is 5. 
Result so far: 185.0
Subtracting 770 from 921 leaves us with 151.
Append the next digit (7) from the dividend to 151 and continue with: 1517 / 154

Step 6:
1517 divided by 154 is 9 with a remainder of 131.
Use 9 as the next digit of our solution. 
Result so far: 1859.0
The remainder is 131 after subtracting 1386 from 1517.
Take the next digit (4) from the dividend and append it to 131, then repeat: 1314 / 154

Advancing to step 7:
154 can be fit into 1314 8 times, resulting in a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 18598.0
If we take 1232 away from 1314, we end up with 82.
Take the next digit (0) from the dividend and append it to 82, then repeat: 820 / 154

Advancing to step 8:
If we divide 820 by 154, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 185985.0
If we take 770 away from 820, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
154 goes into 500 3 times with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 185985.3
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
If we divide 380 by 154, we get 2 and a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 185985.32
If we take 308 away from 380, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
If we divide 720 by 154, we get 4 and a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 185985.324
Deduct 616 from 720 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 12:
When dividing 1040 by 154, we get 6 with a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 185985.3246
Subtract 924 from 1040 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 13:
When dividing 1160 by 154, we get 7 with a remainder of 82.
Record the quotient 7 as the next digit in the result. 
Result so far: 185985.32467
Deduct 1078 from 1160 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 14:
When dividing 820 by 154, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 185985.324675
Subtracting 770 from 820 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 15:
154 can be fit into 500 3 times, resulting in a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 185985.3246753
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 16:
The number 154 fits into 380 2 times, leaving a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 185985.32467532
The remainder is 72 after subtracting 308 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 185985.32467532 with a remaining 7.2e-08.
