59053142 ÷ 161 
The aim is to understand the frequency of 161 in 59053142.

Going ahead to step 1:
If we divide 5 by 161, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 161

Moving on to step 2:
The number 161 fits into 59 0 times, leaving a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 59 leaves us with 59.
Take the next digit (0) from the dividend and append it to 59, then repeat: 590 / 161

Moving on to step 3:
If we divide 590 by 161, we get 3 and a remainder of 107.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 483 from 590 leaves us with 107.
Take the next digit (5) from the dividend and append it to 107, then repeat: 1075 / 161

Step 4:
161 can be fit into 1075 6 times, resulting in a remainder of 109.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 109 after subtracting 966 from 1075.
Grab the next digit (3) from the dividend, add it to 109, then carry on: 1093 / 161

On to step 5:
If we divide 1093 by 161, we get 6 and a remainder of 127.
Use 6 as the next digit of our solution. 
Result so far: 366.0
If we take 966 away from 1093, we end up with 127.
Include the next digit (1) from the dividend after 127, then repeat: 1271 / 161

On to step 6:
1271 divided by 161 is 7 with a remainder of 144.
The next digit of our result is 7. 
Result so far: 3667.0
The remainder is 144 after subtracting 1127 from 1271.
Take the next digit (4) from the dividend and append it to 144, then repeat: 1444 / 161

On to step 7:
161 can be fit into 1444 8 times, resulting in a remainder of 156.
Record the quotient 8 as the next digit in the result. 
Result so far: 36678.0
If we take 1288 away from 1444, we end up with 156.
Include the next digit (2) from the dividend after 156, then repeat: 1562 / 161

Going ahead to step 8:
When dividing 1562 by 161, we get 9 with a remainder of 113.
Put 9 as the next digit of the answer. 
Result so far: 366789.0
The remainder is 113 after subtracting 1449 from 1562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 9:
161 can be fit into 1130 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 366789.7
Subtracting 1127 from 1130 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
161 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 366789.7
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
300 divided by 161 is 1 with a remainder of 139.
Use 1 as the next digit of our solution. 
Result so far: 366789.701
Subtract 161 from 300 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 12:
If we divide 1390 by 161, we get 8 and a remainder of 102.
Put 8 as the next digit of the answer. 
Result so far: 366789.7018
Deduct 1288 from 1390 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 13:
The number 161 fits into 1020 6 times, leaving a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 366789.70186
Subtracting 966 from 1020 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 14:
The number 161 fits into 540 3 times, leaving a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 366789.701863
Subtracting 483 from 540 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 15:
570 divided by 161 is 3 with a remainder of 87.
The next digit of our result is 3. 
Result so far: 366789.7018633
If we subtract 483 from 570, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Our division results in 366789.7018633 with a remaining 8.7e-07.
