10909571 divided by 122 
The aim is to understand the frequency of 122 in 10909571.

On to step 1:
122 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 122

Advancing to step 2:
The number 122 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 122

Let's proceed to step 3:
The number 122 fits into 109 0 times, leaving a remainder of 109.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 109 leaves us with 109.
Append the next digit (0) from the dividend to 109 and continue with: 1090 / 122

Advancing to step 4:
122 can be fit into 1090 8 times, resulting in a remainder of 114.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 976 from 1090, we get 114.
Include the next digit (9) from the dividend after 114, then repeat: 1149 / 122

Going ahead to step 5:
1149 divided by 122 is 9 with a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Deduct 1098 from 1149 and we're left with 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 122

On to step 6:
When dividing 515 by 122, we get 4 with a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 894.0
The remainder is 27 after subtracting 488 from 515.
Take the next digit (7) from the dividend and append it to 27, then repeat: 277 / 122

Advancing to step 7:
122 can be fit into 277 2 times, resulting in a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 8942.0
If we take 244 away from 277, we end up with 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 122

Step 8:
331 divided by 122 is 2 with a remainder of 87.
Put 2 as the next digit of the answer. 
Result so far: 89422.0
If we subtract 244 from 331, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 9:
The number 122 fits into 870 7 times, leaving a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 89422.7
The remainder is 16 after subtracting 854 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
122 can be fit into 160 1 times, resulting in a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 89422.71
Subtracting 122 from 160 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
When dividing 380 by 122, we get 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 89422.713
Subtract 366 from 380 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
140 divided by 122 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 89422.7131
If we subtract 122 from 140, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
If we divide 180 by 122, we get 1 and a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 89422.71311
Deduct 122 from 180 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 89422.71311, with a leftover of 5.8e-05.
