We look at the division of 92712439 by 861 
The aim is to understand the frequency of 861 in 92712439.

Step 1:
If we divide 9 by 861, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 861

Step 2:
861 goes into 92 0 times with a remainder of 92.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 92, we get 92.
Take the next digit (7) from the dividend and append it to 92, then repeat: 927 / 861

Let's proceed to step 3:
The number 861 fits into 927 1 times, leaving a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 861 from 927 and we're left with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 861

Step 4:
861 can be fit into 661 0 times, resulting in a remainder of 661.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 661 to get 661.
Append the next digit (2) from the dividend to 661 and continue with: 6612 / 861

Moving on to step 5:
When dividing 6612 by 861, we get 7 with a remainder of 585.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Subtract 6027 from 6612 to get 585.
Fetch the next digit (4) from the dividend, attach it to 585 and continue: 5854 / 861

Going ahead to step 6:
When dividing 5854 by 861, we get 6 with a remainder of 688.
Use 6 as the next digit of our solution. 
Result so far: 1076.0
Subtracting 5166 from 5854 leaves us with 688.
Grab the next digit (3) from the dividend, add it to 688, then carry on: 6883 / 861

Moving on to step 7:
The number 861 fits into 6883 7 times, leaving a remainder of 856.
The next digit of our result is 7. 
Result so far: 10767.0
If we take 6027 away from 6883, we end up with 856.
Fetch the next digit (9) from the dividend, attach it to 856 and continue: 8569 / 861

Step 8:
The number 861 fits into 8569 9 times, leaving a remainder of 820.
Record the quotient 9 as the next digit in the result. 
Result so far: 107679.0
The remainder is 820 after subtracting 7749 from 8569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Let's proceed to step 9:
8200 divided by 861 is 9 with a remainder of 451.
Put 9 as the next digit of the answer. 
Result so far: 107679.9
If we take 7749 away from 8200, we end up with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Going ahead to step 10:
861 can be fit into 4510 5 times, resulting in a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 107679.95
If we subtract 4305 from 4510, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 11:
The number 861 fits into 2050 2 times, leaving a remainder of 328.
Record the quotient 2 as the next digit in the result. 
Result so far: 107679.952
Deduct 1722 from 2050 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 12:
When dividing 3280 by 861, we get 3 with a remainder of 697.
Write down 3 as next digit of the result. 
Result so far: 107679.9523
Deduct 2583 from 3280 and we're left with 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

On to step 13:
When dividing 6970 by 861, we get 8 with a remainder of 82.
The next digit of our result is 8. 
Result so far: 107679.95238
Subtract 6888 from 6970 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 14:
When dividing 820 by 861, we get 0 with a remainder of 820.
Put 0 as the next digit of the answer. 
Result so far: 107679.95238
Subtract 0 from 820 to get 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Let's proceed to step 15:
If we divide 8200 by 861, we get 9 and a remainder of 451.
Use 9 as the next digit of our solution. 
Result so far: 107679.9523809
If we take 7749 away from 8200, we end up with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Step 16:
861 goes into 4510 5 times with a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 107679.95238095
If we take 4305 away from 4510, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The final result is 107679.95238095 with a remainder of 2.05e-07.
