8174490 divided by 161 
We want to figure out the number of times 8174490 can be divided by 161.

Step 1:
8 divided by 161 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 161

On to step 2:
If we divide 81 by 161, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 161

Moving on to step 3:
When dividing 817 by 161, we get 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 12 after subtracting 805 from 817.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 161

Going ahead to step 4:
If we divide 124 by 161, we get 0 and a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 50.0
The remainder is 124 after subtracting 0 from 124.
Include the next digit (4) from the dividend after 124, then repeat: 1244 / 161

Let's proceed to step 5:
When dividing 1244 by 161, we get 7 with a remainder of 117.
Record the quotient 7 as the next digit in the result. 
Result so far: 507.0
Subtract 1127 from 1244 to get 117.
Grab the next digit (9) from the dividend, add it to 117, then carry on: 1179 / 161

Let's proceed to step 6:
161 goes into 1179 7 times with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 5077.0
Deduct 1127 from 1179 and we're left with 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 161

On to step 7:
520 divided by 161 is 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 50773.0
If we subtract 483 from 520, we 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 8:
The number 161 fits into 370 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 50773.2
If we subtract 322 from 370, we 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.

On to step 9:
161 goes into 480 2 times with a remainder of 158.
Write down 2 as next digit of the result. 
Result so far: 50773.22
Subtract 322 from 480 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Our division results in 50773.22 with a remaining 0.158.
