We look at the division of 735671 by 61 
The aim is to understand the frequency of 61 in 735671.

On to step 1:
61 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 61

Step 2:
If we divide 73 by 61, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 61 from 73 and we're left with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 61

Moving on to step 3:
125 divided by 61 is 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 3 after subtracting 122 from 125.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 61

Advancing to step 4:
61 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
The remainder is 36 after subtracting 0 from 36.
Bring next digit (7) of the dividend behind the 36 and repeat the process: 367 / 61

Let's proceed to step 5:
61 can be fit into 367 6 times, resulting in a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 1206.0
If we take 366 away from 367, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 61

On to step 6:
11 divided by 61 is 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 12060.0
Deduct 0 from 11 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
If we divide 110 by 61, we get 1 and a remainder of 49.
The next digit of our result is 1. 
Result so far: 12060.1
If we take 61 away from 110, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 8:
61 goes into 490 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 12060.18
If we subtract 488 from 490, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
If we divide 20 by 61, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 12060.18
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
200 divided by 61 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 12060.1803
Subtracting 183 from 200 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 11:
When dividing 170 by 61, we get 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 12060.18032
Subtracting 122 from 170 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
If we divide 480 by 61, we get 7 and a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 12060.180327
Subtracting 427 from 480 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 13:
61 can be fit into 530 8 times, resulting in a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 12060.1803278
Subtracting 488 from 530 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 14:
61 goes into 420 6 times with a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 12060.18032786
Deduct 366 from 420 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 12060.18032786 and a remainder of 5.4e-08.
