88518394 ÷ 161 
We want to figure out the number of times 88518394 can be divided by 161.

Moving on to step 1:
The number 161 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 161

Step 2:
161 goes into 88 0 times with a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 88 and we're left with 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 161

Advancing to step 3:
When dividing 885 by 161, we get 5 with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 805 from 885 leaves us with 80.
Grab the next digit (1) from the dividend, add it to 80, then carry on: 801 / 161

On to step 4:
If we divide 801 by 161, we get 4 and a remainder of 157.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtract 644 from 801 to get 157.
Grab the next digit (8) from the dividend, add it to 157, then carry on: 1578 / 161

Advancing to step 5:
161 can be fit into 1578 9 times, resulting in a remainder of 129.
Record the quotient 9 as the next digit in the result. 
Result so far: 549.0
If we take 1449 away from 1578, we end up with 129.
Fetch the next digit (3) from the dividend, attach it to 129 and continue: 1293 / 161

Advancing to step 6:
If we divide 1293 by 161, we get 8 and a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 5498.0
Subtract 1288 from 1293 to get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 161

Going ahead to step 7:
When dividing 59 by 161, we get 0 with a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 54980.0
If we take 0 away from 59, we end up with 59.
Append the next digit (4) from the dividend to 59 and continue with: 594 / 161

Moving on to step 8:
If we divide 594 by 161, we get 3 and a remainder of 111.
Use 3 as the next digit of our solution. 
Result so far: 549803.0
Deduct 483 from 594 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 9:
The number 161 fits into 1110 6 times, leaving a remainder of 144.
Record the quotient 6 as the next digit in the result. 
Result so far: 549803.6
The remainder is 144 after subtracting 966 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 10:
161 goes into 1440 8 times with a remainder of 152.
Use 8 as the next digit of our solution. 
Result so far: 549803.68
Subtracting 1288 from 1440 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 11:
1520 divided by 161 is 9 with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 549803.689
Subtract 1449 from 1520 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 12:
When dividing 710 by 161, we get 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 549803.6894
Deduct 644 from 710 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
The number 161 fits into 660 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 549803.68944
Deduct 644 from 660 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 549803.68944, with a leftover of 1.6e-05.
