70872 divided by 61 
The aim is to understand the frequency of 61 in 70872.

Step 1:
When dividing 7 by 61, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 61

Advancing to step 2:
If we divide 70 by 61, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 61 from 70, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 61

Going ahead to step 3:
61 goes into 98 1 times with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 61 from 98, we get 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 61

Going ahead to step 4:
The number 61 fits into 377 6 times, leaving a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
The remainder is 11 after subtracting 366 from 377.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 61

On to step 5:
61 goes into 112 1 times with a remainder of 51.
The next digit of our result is 1. 
Result so far: 1161.0
Subtracting 61 from 112 leaves us with 51.
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 6:
61 can be fit into 510 8 times, resulting in a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 1161.8
If we take 488 away from 510, we end up 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.

Let's proceed to step 7:
220 divided by 61 is 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 1161.83
If we take 183 away from 220, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
370 divided by 61 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 1161.836
If we take 366 away from 370, we end up with 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 9:
61 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1161.836
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.

Moving on to step 10:
If we divide 400 by 61, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 1161.83606
If we take 366 away from 400, we end up 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.

Going ahead to step 11:
When dividing 340 by 61, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1161.836065
Subtracting 305 from 340 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
61 can be fit into 350 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1161.8360655
Deduct 305 from 350 and we're left with 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 1161.8360655 with a remaining 4.5e-07.
