46340899 ÷ 161 
The aim is to understand the frequency of 161 in 46340899.

On to step 1:
When dividing 4 by 161, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 161

On to step 2:
161 can be fit into 46 0 times, resulting in a remainder of 46.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 46 after subtracting 0 from 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 161

Advancing to step 3:
161 can be fit into 463 2 times, resulting in a remainder of 141.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 322 from 463 to get 141.
Grab the next digit (4) from the dividend, add it to 141, then carry on: 1414 / 161

On to step 4:
If we divide 1414 by 161, we get 8 and a remainder of 126.
Put 8 as the next digit of the answer. 
Result so far: 28.0
The remainder is 126 after subtracting 1288 from 1414.
Grab the next digit (0) from the dividend, add it to 126, then carry on: 1260 / 161

Step 5:
When dividing 1260 by 161, we get 7 with a remainder of 133.
The number 7 becomes the next digit in our result. 
Result so far: 287.0
Subtract 1127 from 1260 to get 133.
Take the next digit (8) from the dividend and append it to 133, then repeat: 1338 / 161

Advancing to step 6:
161 can be fit into 1338 8 times, resulting in a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 2878.0
Deduct 1288 from 1338 and we're left with 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 161

Step 7:
The number 161 fits into 509 3 times, leaving a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 28783.0
If we subtract 483 from 509, we get 26.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 161

Moving on to step 8:
161 goes into 269 1 times with a remainder of 108.
Put 1 as the next digit of the answer. 
Result so far: 287831.0
Subtract 161 from 269 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 9:
The number 161 fits into 1080 6 times, leaving a remainder of 114.
Use 6 as the next digit of our solution. 
Result so far: 287831.6
Deduct 966 from 1080 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 10:
The number 161 fits into 1140 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 287831.67
If we take 1127 away from 1140, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
The number 161 fits into 130 0 times, leaving a remainder of 130.
The next digit of our result is 0. 
Result so far: 287831.67
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 12:
161 goes into 1300 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 287831.6708
Subtract 1288 from 1300 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
When dividing 120 by 161, we get 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 287831.6708
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 14:
161 goes into 1200 7 times with a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 287831.670807
Subtract 1127 from 1200 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 15:
161 can be fit into 730 4 times, resulting in a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 287831.6708074
Deduct 644 from 730 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 16:
161 goes into 860 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 287831.67080745
If we take 805 away from 860, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The quotient of the division is 287831.67080745, and the remainder is 5.5e-08.
