85605097 ÷ 161 
Let's see how many times 161 fits into 85605097.

Advancing to step 1:
The number 161 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 161

Let's proceed to step 2:
When dividing 85 by 161, we get 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Fetch the next digit (6) from the dividend, attach it to 85 and continue: 856 / 161

On to step 3:
161 can be fit into 856 5 times, resulting in a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 805 from 856 and we're left with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 161

Moving on to step 4:
The number 161 fits into 510 3 times, leaving a remainder of 27.
The next digit of our result is 3. 
Result so far: 53.0
If we take 483 away from 510, we end up with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 161

Advancing to step 5:
161 can be fit into 275 1 times, resulting in a remainder of 114.
Write down 1 as next digit of the result. 
Result so far: 531.0
Subtracting 161 from 275 leaves us with 114.
Bring next digit (0) of the dividend behind the 114 and repeat the process: 1140 / 161

On to step 6:
The number 161 fits into 1140 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 5317.0
If we take 1127 away from 1140, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 161

Moving on to step 7:
139 divided by 161 is 0 with a remainder of 139.
Put 0 as the next digit of the answer. 
Result so far: 53170.0
Deduct 0 from 139 and we're left with 139.
Fetch the next digit (7) from the dividend, attach it to 139 and continue: 1397 / 161

Going ahead to step 8:
161 goes into 1397 8 times with a remainder of 109.
The next digit of our result is 8. 
Result so far: 531708.0
Subtract 1288 from 1397 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Moving on to step 9:
1090 divided by 161 is 6 with a remainder of 124.
Record the quotient 6 as the next digit in the result. 
Result so far: 531708.6
If we take 966 away from 1090, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 10:
If we divide 1240 by 161, we get 7 and a remainder of 113.
The number 7 becomes the next digit in our result. 
Result so far: 531708.67
The remainder is 113 after subtracting 1127 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 11:
The number 161 fits into 1130 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 531708.677
The remainder is 3 after subtracting 1127 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 531708.677 and a remainder of 0.0003.
