We divide 18356835 by 997
The aim is to understand the frequency of 997 in 18356835.

Let's proceed to step 1:
The number 997 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 997

Moving on to step 2:
When dividing 18 by 997, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 997

Advancing to step 3:
997 can be fit into 183 0 times, resulting in a remainder of 183.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 183, we end up with 183.
Grab the next digit (5) from the dividend, add it to 183, then carry on: 1835 / 997

Step 4:
1835 divided by 997 is 1 with a remainder of 838.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 997 from 1835 leaves us with 838.
Grab the next digit (6) from the dividend, add it to 838, then carry on: 8386 / 997

Advancing to step 5:
997 can be fit into 8386 8 times, resulting in a remainder of 410.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 7976 from 8386 and we're left with 410.
Include the next digit (8) from the dividend after 410, then repeat: 4108 / 997

Moving on to step 6:
997 goes into 4108 4 times with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
If we subtract 3988 from 4108, we get 120.
Fetch the next digit (3) from the dividend, attach it to 120 and continue: 1203 / 997

Going ahead to step 7:
The number 997 fits into 1203 1 times, leaving a remainder of 206.
Write down 1 as next digit of the result. 
Result so far: 1841.0
If we take 997 away from 1203, we end up with 206.
Fetch the next digit (5) from the dividend, attach it to 206 and continue: 2065 / 997

Step 8:
The number 997 fits into 2065 2 times, leaving a remainder of 71.
Put 2 as the next digit of the answer. 
Result so far: 18412.0
If we subtract 1994 from 2065, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 9:
When dividing 710 by 997, we get 0 with a remainder of 710.
Write down 0 as next digit of the result. 
Result so far: 18412.0
Deduct 0 from 710 and we're left with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Step 10:
If we divide 7100 by 997, we get 7 and a remainder of 121.
The number 7 becomes the next digit in our result. 
Result so far: 18412.07
Subtract 6979 from 7100 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 11:
The number 997 fits into 1210 1 times, leaving a remainder of 213.
The next digit of our result is 1. 
Result so far: 18412.071
If we subtract 997 from 1210, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Advancing to step 12:
The number 997 fits into 2130 2 times, leaving a remainder of 136.
The number 2 becomes the next digit in our result. 
Result so far: 18412.0712
Deduct 1994 from 2130 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 13:
The number 997 fits into 1360 1 times, leaving a remainder of 363.
The next digit of our result is 1. 
Result so far: 18412.07121
Deduct 997 from 1360 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Going ahead to step 14:
997 goes into 3630 3 times with a remainder of 639.
The next digit of our result is 3. 
Result so far: 18412.071213
Deduct 2991 from 3630 and we're left with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Step 15:
997 goes into 6390 6 times with a remainder of 408.
Put 6 as the next digit of the answer. 
Result so far: 18412.0712136
Subtracting 5982 from 6390 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 16:
When dividing 4080 by 997, we get 4 with a remainder of 92.
Write down 4 as next digit of the result. 
Result so far: 18412.07121364
If we take 3988 away from 4080, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final result is 18412.07121364 with a remainder of 9.2e-08.
