We look at the division of 89119193 by 861 
The aim is to understand the frequency of 861 in 89119193.

Moving on to step 1:
8 divided by 861 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 861

Advancing to step 2:
861 can be fit into 89 0 times, resulting in a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Append the next digit (1) from the dividend to 89 and continue with: 891 / 861

Step 3:
When dividing 891 by 861, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 861 from 891 leaves us with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 861

Advancing to step 4:
When dividing 301 by 861, we get 0 with a remainder of 301.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 301 after subtracting 0 from 301.
Include the next digit (9) from the dividend after 301, then repeat: 3019 / 861

Step 5:
When dividing 3019 by 861, we get 3 with a remainder of 436.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we take 2583 away from 3019, we end up with 436.
Include the next digit (1) from the dividend after 436, then repeat: 4361 / 861

Advancing to step 6:
When dividing 4361 by 861, we get 5 with a remainder of 56.
Put 5 as the next digit of the answer. 
Result so far: 1035.0
Subtract 4305 from 4361 to get 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 861

Going ahead to step 7:
If we divide 569 by 861, we get 0 and a remainder of 569.
Put 0 as the next digit of the answer. 
Result so far: 10350.0
Deduct 0 from 569 and we're left with 569.
Bring next digit (3) of the dividend behind the 569 and repeat the process: 5693 / 861

On to step 8:
5693 divided by 861 is 6 with a remainder of 527.
Put 6 as the next digit of the answer. 
Result so far: 103506.0
If we subtract 5166 from 5693, we get 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

On to step 9:
5270 divided by 861 is 6 with a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 103506.6
Subtracting 5166 from 5270 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 10:
The number 861 fits into 1040 1 times, leaving a remainder of 179.
Put 1 as the next digit of the answer. 
Result so far: 103506.61
Deduct 861 from 1040 and we're left with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Let's proceed to step 11:
861 can be fit into 1790 2 times, resulting in a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 103506.612
If we subtract 1722 from 1790, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 12:
The number 861 fits into 680 0 times, leaving a remainder of 680.
Put 0 as the next digit of the answer. 
Result so far: 103506.612
Subtract 0 from 680 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

On to step 13:
If we divide 6800 by 861, we get 7 and a remainder of 773.
The number 7 becomes the next digit in our result. 
Result so far: 103506.61207
Subtract 6027 from 6800 to get 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

On to step 14:
861 goes into 7730 8 times with a remainder of 842.
The next digit of our result is 8. 
Result so far: 103506.612078
Subtract 6888 from 7730 to get 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Step 15:
If we divide 8420 by 861, we get 9 and a remainder of 671.
Use 9 as the next digit of our solution. 
Result so far: 103506.6120789
Subtracting 7749 from 8420 leaves us with 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

On to step 16:
861 can be fit into 6710 7 times, resulting in a remainder of 683.
Record the quotient 7 as the next digit in the result. 
Result so far: 103506.61207897
If we subtract 6027 from 6710, we get 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

The final outcome is 103506.61207897, with a leftover of 6.83e-07.
