We divide 38787622 by 991
The aim is to understand the frequency of 991 in 38787622.

Let's proceed to step 1:
991 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 991

Step 2:
991 can be fit into 38 0 times, resulting in a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 991

Advancing to step 3:
If we divide 387 by 991, we get 0 and a remainder of 387.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 387 and we're left with 387.
Take the next digit (8) from the dividend and append it to 387, then repeat: 3878 / 991

On to step 4:
When dividing 3878 by 991, we get 3 with a remainder of 905.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 2973 from 3878, we get 905.
Take the next digit (7) from the dividend and append it to 905, then repeat: 9057 / 991

Advancing to step 5:
991 goes into 9057 9 times with a remainder of 138.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we subtract 8919 from 9057, we get 138.
Grab the next digit (6) from the dividend, add it to 138, then carry on: 1386 / 991

Step 6:
When dividing 1386 by 991, we get 1 with a remainder of 395.
Use 1 as the next digit of our solution. 
Result so far: 391.0
Deduct 991 from 1386 and we're left with 395.
Bring next digit (2) of the dividend behind the 395 and repeat the process: 3952 / 991

Moving on to step 7:
If we divide 3952 by 991, we get 3 and a remainder of 979.
Write down 3 as next digit of the result. 
Result so far: 3913.0
If we subtract 2973 from 3952, we get 979.
Grab the next digit (2) from the dividend, add it to 979, then carry on: 9792 / 991

Advancing to step 8:
When dividing 9792 by 991, we get 9 with a remainder of 873.
The number 9 becomes the next digit in our result. 
Result so far: 39139.0
If we take 8919 away from 9792, we end up with 873.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8730, and continue the process.

Going ahead to step 9:
8730 divided by 991 is 8 with a remainder of 802.
The number 8 becomes the next digit in our result. 
Result so far: 39139.8
If we subtract 7928 from 8730, we get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Going ahead to step 10:
991 goes into 8020 8 times with a remainder of 92.
Use 8 as the next digit of our solution. 
Result so far: 39139.88
If we take 7928 away from 8020, 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.

Our division results in 39139.88 with a remaining 0.092.
