We're dividing 87948002 by 61 
The aim is to understand the frequency of 61 in 87948002.

Step 1:
8 divided by 61 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 61

Going ahead to step 2:
If we divide 87 by 61, we get 1 and a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 61 away from 87, we end up with 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 61

Step 3:
If we divide 269 by 61, we get 4 and a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 244 from 269, we get 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 61

Advancing to step 4:
61 goes into 254 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 144.0
If we take 244 away from 254, we end up with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 61

Advancing to step 5:
108 divided by 61 is 1 with a remainder of 47.
The next digit of our result is 1. 
Result so far: 1441.0
If we take 61 away from 108, we end up with 47.
Bring next digit (0) of the dividend behind the 47 and repeat the process: 470 / 61

Moving on to step 6:
61 goes into 470 7 times with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 14417.0
If we subtract 427 from 470, we get 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 61

Advancing to step 7:
If we divide 430 by 61, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 144177.0
If we take 427 away from 430, we end up with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 61

Going ahead to step 8:
The number 61 fits into 32 0 times, leaving a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 1441770.0
If we take 0 away from 32, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
320 divided by 61 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1441770.5
The remainder is 15 after subtracting 305 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
The number 61 fits into 150 2 times, leaving a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 1441770.52
If we subtract 122 from 150, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
61 can be fit into 280 4 times, resulting in a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 1441770.524
The remainder is 36 after subtracting 244 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
61 goes into 360 5 times with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 1441770.5245
The remainder is 55 after subtracting 305 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 13:
If we divide 550 by 61, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1441770.52459
If we take 549 away from 550, 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.

Moving on to step 14:
The number 61 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1441770.52459
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 15:
The number 61 fits into 100 1 times, leaving a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1441770.5245901
Subtract 61 from 100 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 16:
When dividing 390 by 61, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 1441770.52459016
Subtracting 366 from 390 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 1441770.52459016 and a remainder of 2.4e-08.
