We divide 171907 by 61
The aim is to understand the frequency of 61 in 171907.

Advancing to step 1:
1 divided by 61 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 61

Let's proceed to step 2:
When dividing 17 by 61, we get 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 61

Moving on to step 3:
171 divided by 61 is 2 with a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 122 from 171 leaves us with 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 61

On to step 4:
61 can be fit into 499 8 times, resulting in a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we subtract 488 from 499, we get 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 61

Step 5:
61 can be fit into 110 1 times, resulting in a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 281.0
Subtracting 61 from 110 leaves us with 49.
Grab the next digit (7) from the dividend, add it to 49, then carry on: 497 / 61

On to step 6:
61 can be fit into 497 8 times, resulting in a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 2818.0
If we take 488 away from 497, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
61 can be fit into 90 1 times, resulting in a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 2818.1
The remainder is 29 after subtracting 61 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 8:
The number 61 fits into 290 4 times, leaving a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 2818.14
Subtract 244 from 290 to 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.

On to step 9:
61 goes into 460 7 times with a remainder of 33.
The next digit of our result is 7. 
Result so far: 2818.147
Subtracting 427 from 460 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 10:
61 can be fit into 330 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 2818.1475
If we subtract 305 from 330, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
250 divided by 61 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 2818.14754
The remainder is 6 after subtracting 244 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
60 divided by 61 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 2818.14754
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
61 can be fit into 600 9 times, resulting in a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 2818.1475409
Subtract 549 from 600 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 14:
61 goes into 510 8 times with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 2818.14754098
If we subtract 488 from 510, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 2818.14754098 with a balance of 2.2e-08.
