Let's divide 66908479 by 161
The aim is to understand the frequency of 161 in 66908479.

Let's proceed to step 1:
The number 161 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 161

Going ahead to step 2:
When dividing 66 by 161, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 161

Going ahead to step 3:
669 divided by 161 is 4 with a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 644 from 669, we get 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 161

Let's proceed to step 4:
250 divided by 161 is 1 with a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Subtracting 161 from 250 leaves us with 89.
Append the next digit (8) from the dividend to 89 and continue with: 898 / 161

On to step 5:
When dividing 898 by 161, we get 5 with a remainder of 93.
Write down 5 as next digit of the result. 
Result so far: 415.0
The remainder is 93 after subtracting 805 from 898.
Fetch the next digit (4) from the dividend, attach it to 93 and continue: 934 / 161

Advancing to step 6:
If we divide 934 by 161, we get 5 and a remainder of 129.
Use 5 as the next digit of our solution. 
Result so far: 4155.0
Subtracting 805 from 934 leaves us with 129.
Take the next digit (7) from the dividend and append it to 129, then repeat: 1297 / 161

Moving on to step 7:
The number 161 fits into 1297 8 times, leaving a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 41558.0
Subtract 1288 from 1297 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 161

Advancing to step 8:
161 can be fit into 99 0 times, resulting in a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 415580.0
If we take 0 away from 99, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 9:
161 goes into 990 6 times with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 415580.6
Subtracting 966 from 990 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
The number 161 fits into 240 1 times, leaving a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 415580.61
If we take 161 away from 240, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 11:
If we divide 790 by 161, we get 4 and a remainder of 146.
Put 4 as the next digit of the answer. 
Result so far: 415580.614
Subtracting 644 from 790 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 12:
The number 161 fits into 1460 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 415580.6149
The remainder is 11 after subtracting 1449 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
The number 161 fits into 110 0 times, leaving a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 415580.6149
The remainder is 110 after subtracting 0 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 14:
The number 161 fits into 1100 6 times, leaving a remainder of 134.
Write down 6 as next digit of the result. 
Result so far: 415580.614906
The remainder is 134 after subtracting 966 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 15:
161 goes into 1340 8 times with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 415580.6149068
The remainder is 52 after subtracting 1288 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 16:
161 goes into 520 3 times with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 415580.61490683
If we take 483 away from 520, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

In conclusion, the division gives 415580.61490683 with a balance of 3.7e-08.
