38021638 ÷ 154 
We want to figure out the number of times 38021638 can be divided by 154.

Let's proceed to step 1:
The number 154 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 154

Going ahead to step 2:
154 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 154

Let's proceed to step 3:
154 can be fit into 380 2 times, resulting in a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 308 away from 380, we end up with 72.
Grab the next digit (2) from the dividend, add it to 72, then carry on: 722 / 154

Advancing to step 4:
When dividing 722 by 154, we get 4 with a remainder of 106.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 616 away from 722, we end up with 106.
Include the next digit (1) from the dividend after 106, then repeat: 1061 / 154

Moving on to step 5:
When dividing 1061 by 154, we get 6 with a remainder of 137.
The next digit of our result is 6. 
Result so far: 246.0
If we subtract 924 from 1061, we get 137.
Fetch the next digit (6) from the dividend, attach it to 137 and continue: 1376 / 154

On to step 6:
The number 154 fits into 1376 8 times, leaving a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 2468.0
Subtract 1232 from 1376 to get 144.
Take the next digit (3) from the dividend and append it to 144, then repeat: 1443 / 154

Advancing to step 7:
154 goes into 1443 9 times with a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 24689.0
Subtract 1386 from 1443 to get 57.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 154

Step 8:
154 can be fit into 578 3 times, resulting in a remainder of 116.
Put 3 as the next digit of the answer. 
Result so far: 246893.0
The remainder is 116 after subtracting 462 from 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 9:
154 can be fit into 1160 7 times, resulting in a remainder of 82.
Use 7 as the next digit of our solution. 
Result so far: 246893.7
If we take 1078 away from 1160, we end up 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.

Step 10:
154 can be fit into 820 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 246893.75
Deduct 770 from 820 and we're left 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.

Moving on to step 11:
154 goes into 500 3 times with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 246893.753
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
154 goes into 380 2 times with a remainder of 72.
The next digit of our result is 2. 
Result so far: 246893.7532
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.

Advancing to step 13:
When dividing 720 by 154, we get 4 with a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 246893.75324
Subtracting 616 from 720 leaves us 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 14:
The number 154 fits into 1040 6 times, leaving a remainder of 116.
The next digit of our result is 6. 
Result so far: 246893.753246
Deduct 924 from 1040 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 15:
The number 154 fits into 1160 7 times, leaving a remainder of 82.
Use 7 as the next digit of our solution. 
Result so far: 246893.7532467
The remainder is 82 after subtracting 1078 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 16:
154 goes into 820 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 246893.75324675
Deduct 770 from 820 and we're left 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.

The final outcome is 246893.75324675, with a leftover of 5e-08.
