We're dividing 151091 by 38 
Let's see how many times 38 fits into 151091.

On to step 1:
The number 38 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 38

Moving on to step 2:
When dividing 15 by 38, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 38

Moving on to step 3:
When dividing 151 by 38, we get 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 114 from 151, we get 37.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 38

Advancing to step 4:
When dividing 370 by 38, we get 9 with a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
The remainder is 28 after subtracting 342 from 370.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 38

Let's proceed to step 5:
38 can be fit into 289 7 times, resulting in a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 397.0
Subtracting 266 from 289 leaves us with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 38

Let's proceed to step 6:
When dividing 231 by 38, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 3976.0
Deduct 228 from 231 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 38, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 3976.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
The number 38 fits into 300 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 3976.07
If we take 266 away from 300, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
If we divide 340 by 38, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 3976.078
If we take 304 away from 340, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
360 divided by 38 is 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 3976.0789
The remainder is 18 after subtracting 342 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
180 divided by 38 is 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 3976.07894
The remainder is 28 after subtracting 152 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
280 divided by 38 is 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 3976.078947
Deduct 266 from 280 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
140 divided by 38 is 3 with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 3976.0789473
Subtract 114 from 140 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
38 can be fit into 260 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 3976.07894736
If we take 228 away from 260, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 3976.07894736 and a remainder of 3.2e-08.
