We're dividing 16161475 by 161 
We want to figure out the number of times 16161475 can be divided by 161.

Step 1:
161 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 161

On to step 2:
If we divide 16 by 161, we get 0 and 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.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 161

Let's proceed to step 3:
When dividing 161 by 161, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 161 from 161.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 161

Let's proceed to step 4:
If we divide 6 by 161, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 161

Moving on to step 5:
When dividing 61 by 161, we get 0 with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtracting 0 from 61 leaves us with 61.
Include the next digit (4) from the dividend after 61, then repeat: 614 / 161

Step 6:
When dividing 614 by 161, we get 3 with a remainder of 131.
The next digit of our result is 3. 
Result so far: 1003.0
Subtracting 483 from 614 leaves us with 131.
Append the next digit (7) from the dividend to 131 and continue with: 1317 / 161

Moving on to step 7:
The number 161 fits into 1317 8 times, leaving a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 10038.0
If we take 1288 away from 1317, we end up with 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 161

On to step 8:
If we divide 295 by 161, we get 1 and a remainder of 134.
The next digit of our result is 1. 
Result so far: 100381.0
Subtracting 161 from 295 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 9:
If we divide 1340 by 161, we get 8 and a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 100381.8
Deduct 1288 from 1340 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
If we divide 520 by 161, we get 3 and a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 100381.83
Subtract 483 from 520 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
When dividing 370 by 161, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 100381.832
Subtract 322 from 370 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
480 divided by 161 is 2 with a remainder of 158.
Use 2 as the next digit of our solution. 
Result so far: 100381.8322
If we take 322 away from 480, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

After the division, we end up with 100381.8322 and a remainder of 0.00158.
