We're dividing 845644 by 61 
The aim is to understand the frequency of 61 in 845644.

Advancing 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.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 61

Going ahead to step 2:
84 divided by 61 is 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 61 from 84 leaves us with 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 61

Let's proceed to step 3:
235 divided by 61 is 3 with a remainder of 52.
The next digit of our result is 3. 
Result so far: 13.0
If we take 183 away from 235, we end up with 52.
Take the next digit (6) from the dividend and append it to 52, then repeat: 526 / 61

Let's proceed to step 4:
61 can be fit into 526 8 times, resulting in a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
If we take 488 away from 526, we end up with 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 61

Step 5:
61 goes into 384 6 times with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 1386.0
If we subtract 366 from 384, we get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 61

Let's proceed to step 6:
61 goes into 184 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 13863.0
If we take 183 away from 184, 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.

Let's proceed to step 7:
The number 61 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13863.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 61, we get 1 and a remainder of 39.
The next digit of our result is 1. 
Result so far: 13863.01
If we take 61 away from 100, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
If we divide 390 by 61, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 13863.016
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.

Going ahead to step 10:
61 can be fit into 240 3 times, resulting in a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 13863.0163
Subtract 183 from 240 to 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.

On to step 11:
If we divide 570 by 61, we get 9 and a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 13863.01639
Subtracting 549 from 570 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
If we divide 210 by 61, we get 3 and a remainder of 27.
The next digit of our result is 3. 
Result so far: 13863.016393
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.

Let's proceed to step 13:
When dividing 270 by 61, we get 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 13863.0163934
If we take 244 away from 270, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
If we divide 260 by 61, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 13863.01639344
Subtracting 244 from 260 leaves us 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.

The final result is 13863.01639344 with a remainder of 1.6e-08.
