38649157 ÷ 138 
We want to divide 38649157 by 138.

Moving on to step 1:
138 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 138

Going ahead to step 2:
138 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 138

Going ahead to step 3:
386 divided by 138 is 2 with a remainder of 110.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 110 after subtracting 276 from 386.
Include the next digit (4) from the dividend after 110, then repeat: 1104 / 138

Going ahead to step 4:
138 goes into 1104 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 1104 away from 1104, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 138

Moving on to step 5:
9 divided by 138 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 280.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 138

Step 6:
If we divide 91 by 138, we get 0 and a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 2800.0
Deduct 0 from 91 and we're left with 91.
Append the next digit (5) from the dividend to 91 and continue with: 915 / 138

Advancing to step 7:
915 divided by 138 is 6 with a remainder of 87.
Put 6 as the next digit of the answer. 
Result so far: 28006.0
If we subtract 828 from 915, we get 87.
Fetch the next digit (7) from the dividend, attach it to 87 and continue: 877 / 138

Let's proceed to step 8:
138 can be fit into 877 6 times, resulting in a remainder of 49.
Put 6 as the next digit of the answer. 
Result so far: 280066.0
If we take 828 away from 877, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
138 can be fit into 490 3 times, resulting in a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 280066.3
If we take 414 away from 490, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
If we divide 760 by 138, we get 5 and a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 280066.35
If we take 690 away from 760, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
138 can be fit into 700 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 280066.355
The remainder is 10 after subtracting 690 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 280066.355, with a leftover of 0.001.
