843631 ÷ 61 
The aim is to understand the frequency of 61 in 843631.

Advancing to step 1:
When dividing 8 by 61, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 61

Step 2:
If we divide 84 by 61, we get 1 and a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 61 from 84, we get 23.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 61

Advancing to step 3:
The number 61 fits into 233 3 times, leaving a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 183 from 233 leaves us with 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 61

Step 4:
When dividing 506 by 61, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we take 488 away from 506, we end up with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 61

On to step 5:
When dividing 183 by 61, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 1383.0
The remainder is 0 after subtracting 183 from 183.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 61

Step 6:
61 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 13830.0
If we take 0 away from 1, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
61 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13830.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 61, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 13830.01
Subtract 61 from 100 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
390 divided by 61 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 13830.016
Subtract 366 from 390 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
The number 61 fits into 240 3 times, leaving a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 13830.0163
If we subtract 183 from 240, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 11:
61 goes into 570 9 times with a remainder of 21.
The next digit of our result is 9. 
Result so far: 13830.01639
Subtract 549 from 570 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 12:
If we divide 210 by 61, we get 3 and a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 13830.016393
Subtracting 183 from 210 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 13:
270 divided by 61 is 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 13830.0163934
If we subtract 244 from 270, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
260 divided by 61 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 13830.01639344
If we take 244 away from 260, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 13830.01639344 with a remaining 1.6e-08.
