We're dividing 71361967 by 61 
The aim is to understand the frequency of 61 in 71361967.

Let's proceed to step 1:
61 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 61

On to step 2:
If we divide 71 by 61, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 61 from 71 and we're left with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 61

Step 3:
When dividing 103 by 61, we get 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 61 from 103 and we're left with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 61

Step 4:
61 goes into 426 6 times with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 116.0
Subtracting 366 from 426 leaves us with 60.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 61

Step 5:
61 can be fit into 601 9 times, resulting in a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 1169.0
If we take 549 away from 601, we end up with 52.
Grab the next digit (9) from the dividend, add it to 52, then carry on: 529 / 61

Moving on to step 6:
When dividing 529 by 61, we get 8 with a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 11698.0
If we take 488 away from 529, we end up with 41.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 61

Step 7:
The number 61 fits into 416 6 times, leaving a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 116986.0
Subtract 366 from 416 to get 50.
Append the next digit (7) from the dividend to 50 and continue with: 507 / 61

On to step 8:
When dividing 507 by 61, we get 8 with a remainder of 19.
The next digit of our result is 8. 
Result so far: 1169868.0
Deduct 488 from 507 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
When dividing 190 by 61, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 1169868.3
The remainder is 7 after subtracting 183 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
If we divide 70 by 61, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1169868.31
If we take 61 away from 70, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
61 can be fit into 90 1 times, resulting in a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1169868.311
Deduct 61 from 90 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 1169868.311, and the remainder is 0.0029.
