We're dividing 51671853 by 912 
The aim is to understand the frequency of 912 in 51671853.

Going ahead to step 1:
If we divide 5 by 912, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 912

Moving on to step 2:
If we divide 51 by 912, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 912

Advancing to step 3:
516 divided by 912 is 0 with a remainder of 516.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 516, we get 516.
Grab the next digit (7) from the dividend, add it to 516, then carry on: 5167 / 912

Moving on to step 4:
If we divide 5167 by 912, we get 5 and a remainder of 607.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 4560 from 5167 and we're left with 607.
Bring next digit (1) of the dividend behind the 607 and repeat the process: 6071 / 912

Advancing to step 5:
6071 divided by 912 is 6 with a remainder of 599.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we subtract 5472 from 6071, we get 599.
Fetch the next digit (8) from the dividend, attach it to 599 and continue: 5998 / 912

Step 6:
912 goes into 5998 6 times with a remainder of 526.
Record the quotient 6 as the next digit in the result. 
Result so far: 566.0
If we take 5472 away from 5998, we end up with 526.
Fetch the next digit (5) from the dividend, attach it to 526 and continue: 5265 / 912

Step 7:
When dividing 5265 by 912, we get 5 with a remainder of 705.
The number 5 becomes the next digit in our result. 
Result so far: 5665.0
The remainder is 705 after subtracting 4560 from 5265.
Append the next digit (3) from the dividend to 705 and continue with: 7053 / 912

Moving on to step 8:
When dividing 7053 by 912, we get 7 with a remainder of 669.
Put 7 as the next digit of the answer. 
Result so far: 56657.0
Deduct 6384 from 7053 and we're left with 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Step 9:
If we divide 6690 by 912, we get 7 and a remainder of 306.
The number 7 becomes the next digit in our result. 
Result so far: 56657.7
The remainder is 306 after subtracting 6384 from 6690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 10:
3060 divided by 912 is 3 with a remainder of 324.
The next digit of our result is 3. 
Result so far: 56657.73
Deduct 2736 from 3060 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 11:
When dividing 3240 by 912, we get 3 with a remainder of 504.
The next digit of our result is 3. 
Result so far: 56657.733
Subtracting 2736 from 3240 leaves us 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.

Our division results in 56657.733 with a remaining 0.0504.
