64703942 ÷ 61 
The aim is to understand the frequency of 61 in 64703942.

On to step 1:
6 divided by 61 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 61

Moving on to step 2:
When dividing 64 by 61, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 61 from 64, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 61

Moving on to step 3:
The number 61 fits into 37 0 times, leaving a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 37 leaves us with 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 61

Advancing to step 4:
61 can be fit into 370 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 106.0
Deduct 366 from 370 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 61

Let's proceed to step 5:
43 divided by 61 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 1060.0
Subtract 0 from 43 to get 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 61

Let's proceed to step 6:
61 can be fit into 439 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 10607.0
If we take 427 away from 439, we end up with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 61

Going ahead to step 7:
The number 61 fits into 124 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 106072.0
Subtracting 122 from 124 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 61

Moving on to step 8:
If we divide 22 by 61, we get 0 and a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 1060720.0
Subtracting 0 from 22 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
220 divided by 61 is 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 1060720.3
The remainder is 37 after subtracting 183 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
61 goes into 370 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 1060720.36
The remainder is 4 after subtracting 366 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
40 divided by 61 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 1060720.36
Deduct 0 from 40 and we're left 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 12:
61 can be fit into 400 6 times, resulting in a remainder of 34.
The next digit of our result is 6. 
Result so far: 1060720.3606
Subtracting 366 from 400 leaves us 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.

Advancing to step 13:
The number 61 fits into 340 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1060720.36065
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.

Moving on to step 14:
61 can be fit into 350 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 1060720.360655
If we subtract 305 from 350, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 1060720.360655 with a remaining 4.5e-06.
