83923994 divided by 161 
We're looking to find how many times 161 goes into 83923994.

Let's proceed to 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
Subtracting 0 from 8 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 161

Let's proceed to step 2:
161 can be fit into 83 0 times, resulting in a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 161

Going ahead to step 3:
161 can be fit into 839 5 times, resulting in a remainder of 34.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 34 after subtracting 805 from 839.
Include the next digit (2) from the dividend after 34, then repeat: 342 / 161

On to step 4:
The number 161 fits into 342 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we take 322 away from 342, we end up with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 161

On to step 5:
161 can be fit into 203 1 times, resulting in a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 521.0
Subtract 161 from 203 to get 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 161

Step 6:
429 divided by 161 is 2 with a remainder of 107.
Put 2 as the next digit of the answer. 
Result so far: 5212.0
If we subtract 322 from 429, we get 107.
Include the next digit (9) from the dividend after 107, then repeat: 1079 / 161

Step 7:
1079 divided by 161 is 6 with a remainder of 113.
Record the quotient 6 as the next digit in the result. 
Result so far: 52126.0
Subtract 966 from 1079 to get 113.
Include the next digit (4) from the dividend after 113, then repeat: 1134 / 161

Let's proceed to step 8:
When dividing 1134 by 161, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 521267.0
Deduct 1127 from 1134 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
70 divided by 161 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 521267.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
161 can be fit into 700 4 times, resulting in a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 521267.04
If we take 644 away from 700, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
If we divide 560 by 161, we get 3 and a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 521267.043
Deduct 483 from 560 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 12:
770 divided by 161 is 4 with a remainder of 126.
The next digit of our result is 4. 
Result so far: 521267.0434
Subtracting 644 from 770 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 13:
1260 divided by 161 is 7 with a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 521267.04347
The remainder is 133 after subtracting 1127 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 14:
161 goes into 1330 8 times with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 521267.043478
Deduct 1288 from 1330 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 15:
420 divided by 161 is 2 with a remainder of 98.
Write down 2 as next digit of the result. 
Result so far: 521267.0434782
Subtracting 322 from 420 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 16:
980 divided by 161 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 521267.04347826
Deduct 966 from 980 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 521267.04347826 with a remainder of 1.4e-08.
