84136651 ÷ 664 
The aim is to understand the frequency of 664 in 84136651.

On to step 1:
664 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 664

Step 2:
If we divide 84 by 664, we get 0 and a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Fetch the next digit (1) from the dividend, attach it to 84 and continue: 841 / 664

On to step 3:
664 goes into 841 1 times with a remainder of 177.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 664 away from 841, we end up with 177.
Fetch the next digit (3) from the dividend, attach it to 177 and continue: 1773 / 664

Advancing to step 4:
If we divide 1773 by 664, we get 2 and a remainder of 445.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 1328 away from 1773, we end up with 445.
Take the next digit (6) from the dividend and append it to 445, then repeat: 4456 / 664

Moving on to step 5:
664 goes into 4456 6 times with a remainder of 472.
The next digit of our result is 6. 
Result so far: 126.0
If we subtract 3984 from 4456, we get 472.
Include the next digit (6) from the dividend after 472, then repeat: 4726 / 664

Moving on to step 6:
If we divide 4726 by 664, we get 7 and a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 1267.0
Subtracting 4648 from 4726 leaves us with 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 664

Moving on to step 7:
When dividing 785 by 664, we get 1 with a remainder of 121.
Use 1 as the next digit of our solution. 
Result so far: 12671.0
The remainder is 121 after subtracting 664 from 785.
Grab the next digit (1) from the dividend, add it to 121, then carry on: 1211 / 664

Going ahead to step 8:
The number 664 fits into 1211 1 times, leaving a remainder of 547.
Write down 1 as next digit of the result. 
Result so far: 126711.0
If we take 664 away from 1211, we end up with 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Advancing to step 9:
If we divide 5470 by 664, we get 8 and a remainder of 158.
Use 8 as the next digit of our solution. 
Result so far: 126711.8
Deduct 5312 from 5470 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 10:
1580 divided by 664 is 2 with a remainder of 252.
Write down 2 as next digit of the result. 
Result so far: 126711.82
Subtract 1328 from 1580 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 11:
2520 divided by 664 is 3 with a remainder of 528.
Record the quotient 3 as the next digit in the result. 
Result so far: 126711.823
If we subtract 1992 from 2520, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

On to step 12:
5280 divided by 664 is 7 with a remainder of 632.
Put 7 as the next digit of the answer. 
Result so far: 126711.8237
The remainder is 632 after subtracting 4648 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Going ahead to step 13:
664 goes into 6320 9 times with a remainder of 344.
Record the quotient 9 as the next digit in the result. 
Result so far: 126711.82379
Subtracting 5976 from 6320 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 14:
If we divide 3440 by 664, we get 5 and a remainder of 120.
Record the quotient 5 as the next digit in the result. 
Result so far: 126711.823795
If we take 3320 away from 3440, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 15:
The number 664 fits into 1200 1 times, leaving a remainder of 536.
Put 1 as the next digit of the answer. 
Result so far: 126711.8237951
Deduct 664 from 1200 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Moving on to step 16:
If we divide 5360 by 664, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 126711.82379518
Deduct 5312 from 5360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 126711.82379518 with a remaining 4.8e-08.
