We look at the division of 61542608 by 860 
The aim is to understand the frequency of 860 in 61542608.

Let's proceed to step 1:
If we divide 6 by 860, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 860

Advancing to step 2:
61 divided by 860 is 0 with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Bring next digit (5) of the dividend behind the 61 and repeat the process: 615 / 860

Let's proceed to step 3:
860 goes into 615 0 times with a remainder of 615.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 615 and we're left with 615.
Include the next digit (4) from the dividend after 615, then repeat: 6154 / 860

Moving on to step 4:
860 can be fit into 6154 7 times, resulting in a remainder of 134.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 6020 from 6154, we get 134.
Take the next digit (2) from the dividend and append it to 134, then repeat: 1342 / 860

Going ahead to step 5:
When dividing 1342 by 860, we get 1 with a remainder of 482.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Deduct 860 from 1342 and we're left with 482.
Include the next digit (6) from the dividend after 482, then repeat: 4826 / 860

Going ahead to step 6:
860 goes into 4826 5 times with a remainder of 526.
Use 5 as the next digit of our solution. 
Result so far: 715.0
If we take 4300 away from 4826, we end up with 526.
Take the next digit (0) from the dividend and append it to 526, then repeat: 5260 / 860

On to step 7:
860 goes into 5260 6 times with a remainder of 100.
Record the quotient 6 as the next digit in the result. 
Result so far: 7156.0
The remainder is 100 after subtracting 5160 from 5260.
Fetch the next digit (8) from the dividend, attach it to 100 and continue: 1008 / 860

Going ahead to step 8:
860 can be fit into 1008 1 times, resulting in a remainder of 148.
Write down 1 as next digit of the result. 
Result so far: 71561.0
If we take 860 away from 1008, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 9:
The number 860 fits into 1480 1 times, leaving a remainder of 620.
Put 1 as the next digit of the answer. 
Result so far: 71561.1
The remainder is 620 after subtracting 860 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 10:
The number 860 fits into 6200 7 times, leaving a remainder of 180.
Use 7 as the next digit of our solution. 
Result so far: 71561.17
Subtracting 6020 from 6200 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
860 goes into 1800 2 times with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 71561.172
The remainder is 80 after subtracting 1720 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
The number 860 fits into 800 0 times, leaving a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 71561.172
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 13:
8000 divided by 860 is 9 with a remainder of 260.
Write down 9 as next digit of the result. 
Result so far: 71561.17209
Subtract 7740 from 8000 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 14:
When dividing 2600 by 860, we get 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 71561.172093
Subtracting 2580 from 2600 leaves us 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 15:
The number 860 fits into 200 0 times, leaving a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 71561.172093
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 16:
860 goes into 2000 2 times with a remainder of 280.
Put 2 as the next digit of the answer. 
Result so far: 71561.17209302
Deduct 1720 from 2000 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 71561.17209302 and a remainder of 2.8e-07.
