837895 ÷ 61 
The aim is to understand the frequency of 61 in 837895.

Let's proceed to step 1:
When dividing 8 by 61, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 61

Going ahead to step 2:
83 divided by 61 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 61 from 83, we get 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 61

Step 3:
If we divide 227 by 61, we get 3 and a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 183 from 227 to get 44.
Append the next digit (8) from the dividend to 44 and continue with: 448 / 61

Moving on to step 4:
When dividing 448 by 61, we get 7 with a remainder of 21.
The next digit of our result is 7. 
Result so far: 137.0
If we take 427 away from 448, we end up with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 61

Moving on to step 5:
61 can be fit into 219 3 times, resulting in a remainder of 36.
The next digit of our result is 3. 
Result so far: 1373.0
Deduct 183 from 219 and we're left with 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 61

On to step 6:
When dividing 365 by 61, we get 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 13735.0
Deduct 305 from 365 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.

Moving on to step 7:
If we divide 600 by 61, we get 9 and a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 13735.9
Subtracting 549 from 600 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 8:
The number 61 fits into 510 8 times, leaving a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 13735.98
Subtract 488 from 510 to 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.

Step 9:
When dividing 220 by 61, we get 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 13735.983
If we take 183 away from 220, 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.

Step 10:
When dividing 370 by 61, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 13735.9836
Subtracting 366 from 370 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
61 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 13735.9836
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
When dividing 400 by 61, we get 6 with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 13735.983606
If we take 366 away from 400, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
When dividing 340 by 61, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 13735.9836065
Subtracting 305 from 340 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 14:
The number 61 fits into 350 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 13735.98360655
Subtracting 305 from 350 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 13735.98360655, with a leftover of 4.5e-08.
