47658231 ÷ 161 
The aim is to understand the frequency of 161 in 47658231.

Going ahead to step 1:
If we divide 4 by 161, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 161

Moving on to step 2:
161 can be fit into 47 0 times, resulting in a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Take the next digit (6) from the dividend and append it to 47, then repeat: 476 / 161

Advancing to step 3:
161 can be fit into 476 2 times, resulting in a remainder of 154.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 322 from 476, we get 154.
Take the next digit (5) from the dividend and append it to 154, then repeat: 1545 / 161

Moving on to step 4:
161 goes into 1545 9 times with a remainder of 96.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Deduct 1449 from 1545 and we're left with 96.
Bring next digit (8) of the dividend behind the 96 and repeat the process: 968 / 161

On to step 5:
968 divided by 161 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 296.0
Subtracting 966 from 968 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 161

Going ahead to step 6:
22 divided by 161 is 0 with a remainder of 22.
The next digit of our result is 0. 
Result so far: 2960.0
If we subtract 0 from 22, we get 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 161

On to step 7:
If we divide 223 by 161, we get 1 and a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 29601.0
The remainder is 62 after subtracting 161 from 223.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 161

Going ahead to step 8:
If we divide 621 by 161, we get 3 and a remainder of 138.
The next digit of our result is 3. 
Result so far: 296013.0
Deduct 483 from 621 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 9:
161 goes into 1380 8 times with a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 296013.8
If we take 1288 away from 1380, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 10:
920 divided by 161 is 5 with a remainder of 115.
The next digit of our result is 5. 
Result so far: 296013.85
Subtract 805 from 920 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 11:
The number 161 fits into 1150 7 times, leaving a remainder of 23.
The next digit of our result is 7. 
Result so far: 296013.857
Deduct 1127 from 1150 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 12:
161 goes into 230 1 times with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 296013.8571
The remainder is 69 after subtracting 161 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 13:
161 can be fit into 690 4 times, resulting in a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 296013.85714
If we subtract 644 from 690, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
When dividing 460 by 161, we get 2 with a remainder of 138.
Use 2 as the next digit of our solution. 
Result so far: 296013.857142
The remainder is 138 after subtracting 322 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 15:
If we divide 1380 by 161, we get 8 and a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 296013.8571428
Deduct 1288 from 1380 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 16:
161 can be fit into 920 5 times, resulting in a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 296013.85714285
If we subtract 805 from 920, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The quotient of the division is 296013.85714285, and the remainder is 1.15e-07.
