83183416 ÷ 161 
The aim is to understand the frequency of 161 in 83183416.

Step 1:
If we divide 8 by 161, we get 0 and 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.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 161

Advancing to step 2:
161 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 161

Going ahead to step 3:
When dividing 831 by 161, we get 5 with a remainder of 26.
The next digit of our result is 5. 
Result so far: 5.0
If we take 805 away from 831, we end up with 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 161

Step 4:
The number 161 fits into 268 1 times, leaving a remainder of 107.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we subtract 161 from 268, we get 107.
Take the next digit (3) from the dividend and append it to 107, then repeat: 1073 / 161

On to step 5:
The number 161 fits into 1073 6 times, leaving a remainder of 107.
The number 6 becomes the next digit in our result. 
Result so far: 516.0
Subtracting 966 from 1073 leaves us with 107.
Append the next digit (4) from the dividend to 107 and continue with: 1074 / 161

Going ahead to step 6:
161 can be fit into 1074 6 times, resulting in a remainder of 108.
Use 6 as the next digit of our solution. 
Result so far: 5166.0
If we take 966 away from 1074, we end up with 108.
Append the next digit (1) from the dividend to 108 and continue with: 1081 / 161

Advancing to step 7:
When dividing 1081 by 161, we get 6 with a remainder of 115.
Use 6 as the next digit of our solution. 
Result so far: 51666.0
Deduct 966 from 1081 and we're left with 115.
Grab the next digit (6) from the dividend, add it to 115, then carry on: 1156 / 161

Advancing to step 8:
1156 divided by 161 is 7 with a remainder of 29.
The next digit of our result is 7. 
Result so far: 516667.0
If we take 1127 away from 1156, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
If we divide 290 by 161, we get 1 and a remainder of 129.
Record the quotient 1 as the next digit in the result. 
Result so far: 516667.1
The remainder is 129 after subtracting 161 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Advancing to step 10:
161 goes into 1290 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 516667.18
If we subtract 1288 from 1290, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
The number 161 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 516667.18
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
200 divided by 161 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 516667.1801
Subtracting 161 from 200 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 13:
161 can be fit into 390 2 times, resulting in a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 516667.18012
Deduct 322 from 390 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 14:
The number 161 fits into 680 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 516667.180124
Deduct 644 from 680 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 15:
360 divided by 161 is 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 516667.1801242
Subtract 322 from 360 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 16:
If we divide 380 by 161, we get 2 and a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 516667.18012422
Deduct 322 from 380 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 516667.18012422, with a leftover of 5.8e-08.
