We look at the division of 161902 by 38 
We want to figure out the number of times 161902 can be divided by 38.

Let's proceed to step 1:
38 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 38

Advancing to step 2:
38 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 38

Advancing to step 3:
38 can be fit into 161 4 times, resulting in a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 9 after subtracting 152 from 161.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 38

Moving on to step 4:
99 divided by 38 is 2 with a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 23 after subtracting 76 from 99.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 38

Advancing to step 5:
If we divide 230 by 38, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 426.0
Deduct 228 from 230 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 38

Going ahead to step 6:
If we divide 22 by 38, we get 0 and a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 4260.0
Deduct 0 from 22 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
If we divide 220 by 38, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 4260.5
Subtract 190 from 220 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
When dividing 300 by 38, we get 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 4260.57
Subtracting 266 from 300 leaves us 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:
38 goes into 340 8 times with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 4260.578
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:
38 goes into 360 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 4260.5789
Deduct 342 from 360 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
When dividing 180 by 38, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 4260.57894
If we subtract 152 from 180, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
38 can be fit into 280 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 4260.578947
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.

Going ahead to step 13:
If we divide 140 by 38, we get 3 and a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 4260.5789473
The remainder is 26 after subtracting 114 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
If we divide 260 by 38, we get 6 and a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 4260.57894736
Subtract 228 from 260 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 4260.57894736 with a remaining 3.2e-08.
