42508752 ÷ 161 
We're looking to find how many times 161 goes into 42508752.

On to step 1:
If we divide 4 by 161, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 161

On to step 2:
The number 161 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 161

Going ahead to step 3:
The number 161 fits into 425 2 times, leaving a remainder of 103.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 322 from 425 leaves us with 103.
Append the next digit (0) from the dividend to 103 and continue with: 1030 / 161

On to step 4:
161 can be fit into 1030 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Deduct 966 from 1030 and we're left with 64.
Append the next digit (8) from the dividend to 64 and continue with: 648 / 161

Let's proceed to step 5:
The number 161 fits into 648 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 264.0
Deduct 644 from 648 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 161

Let's proceed to step 6:
161 can be fit into 47 0 times, resulting in a remainder of 47.
The next digit of our result is 0. 
Result so far: 2640.0
The remainder is 47 after subtracting 0 from 47.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 161

Let's proceed to step 7:
The number 161 fits into 475 2 times, leaving a remainder of 153.
The number 2 becomes the next digit in our result. 
Result so far: 26402.0
Subtracting 322 from 475 leaves us with 153.
Fetch the next digit (2) from the dividend, attach it to 153 and continue: 1532 / 161

Step 8:
When dividing 1532 by 161, we get 9 with a remainder of 83.
The number 9 becomes the next digit in our result. 
Result so far: 264029.0
Subtract 1449 from 1532 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 9:
161 goes into 830 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 264029.5
If we subtract 805 from 830, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
The number 161 fits into 250 1 times, leaving a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 264029.51
Subtracting 161 from 250 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 11:
The number 161 fits into 890 5 times, leaving a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 264029.515
If we take 805 away from 890, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 12:
850 divided by 161 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 264029.5155
The remainder is 45 after subtracting 805 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

In conclusion, the division gives 264029.5155 with a balance of 0.00045.
