We look at the division of 374485 by 61 
The aim is to understand the frequency of 61 in 374485.

Let's proceed to step 1:
The number 61 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 61

On to step 2:
The number 61 fits into 37 0 times, leaving a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 61

On to step 3:
If we divide 374 by 61, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 366 from 374, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 61

On to step 4:
84 divided by 61 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
If we take 61 away from 84, we end up with 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 61

Moving on to step 5:
61 goes into 238 3 times with a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 613.0
The remainder is 55 after subtracting 183 from 238.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 61

On to step 6:
The number 61 fits into 555 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 6139.0
The remainder is 6 after subtracting 549 from 555.
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 7:
60 divided by 61 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 6139.0
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.

Moving on to step 8:
61 can be fit into 600 9 times, resulting in a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 6139.09
The remainder is 51 after subtracting 549 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
When dividing 510 by 61, we get 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 6139.098
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 10:
If we divide 220 by 61, we get 3 and a remainder of 37.
The next digit of our result is 3. 
Result so far: 6139.0983
If we subtract 183 from 220, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 11:
When dividing 370 by 61, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 6139.09836
If we subtract 366 from 370, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
40 divided by 61 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6139.09836
If we take 0 away from 40, we end up 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.

Step 13:
61 goes into 400 6 times with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 6139.0983606
The remainder is 34 after subtracting 366 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
61 goes into 340 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 6139.09836065
Subtract 305 from 340 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 6139.09836065 and a remainder of 3.5e-08.
