Let's divide 81123172 by 934
The aim is to understand the frequency of 934 in 81123172.

Moving on to step 1:
If we divide 8 by 934, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 934

Going ahead to step 2:
934 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 934

Moving on to step 3:
934 goes into 811 0 times with a remainder of 811.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 811 leaves us with 811.
Append the next digit (2) from the dividend to 811 and continue with: 8112 / 934

Moving on to step 4:
8112 divided by 934 is 8 with a remainder of 640.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 7472 from 8112 leaves us with 640.
Take the next digit (3) from the dividend and append it to 640, then repeat: 6403 / 934

Going ahead to step 5:
6403 divided by 934 is 6 with a remainder of 799.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtracting 5604 from 6403 leaves us with 799.
Include the next digit (1) from the dividend after 799, then repeat: 7991 / 934

On to step 6:
The number 934 fits into 7991 8 times, leaving a remainder of 519.
Write down 8 as next digit of the result. 
Result so far: 868.0
Subtract 7472 from 7991 to get 519.
Take the next digit (7) from the dividend and append it to 519, then repeat: 5197 / 934

Moving on to step 7:
934 goes into 5197 5 times with a remainder of 527.
Write down 5 as next digit of the result. 
Result so far: 8685.0
Subtract 4670 from 5197 to get 527.
Fetch the next digit (2) from the dividend, attach it to 527 and continue: 5272 / 934

Going ahead to step 8:
934 goes into 5272 5 times with a remainder of 602.
Use 5 as the next digit of our solution. 
Result so far: 86855.0
Deduct 4670 from 5272 and we're left with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Moving on to step 9:
If we divide 6020 by 934, we get 6 and a remainder of 416.
Record the quotient 6 as the next digit in the result. 
Result so far: 86855.6
If we take 5604 away from 6020, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 10:
When dividing 4160 by 934, we get 4 with a remainder of 424.
Put 4 as the next digit of the answer. 
Result so far: 86855.64
Subtract 3736 from 4160 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 11:
4240 divided by 934 is 4 with a remainder of 504.
Put 4 as the next digit of the answer. 
Result so far: 86855.644
Deduct 3736 from 4240 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

The quotient of the division is 86855.644, and the remainder is 0.0504.
