78772034 ÷ 623 
The aim is to understand the frequency of 623 in 78772034.

On to step 1:
623 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 623

Advancing to step 2:
623 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 623

Advancing to step 3:
623 goes into 787 1 times with a remainder of 164.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 623 from 787 leaves us with 164.
Append the next digit (7) from the dividend to 164 and continue with: 1647 / 623

Going ahead to step 4:
The number 623 fits into 1647 2 times, leaving a remainder of 401.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 1246 away from 1647, we end up with 401.
Include the next digit (2) from the dividend after 401, then repeat: 4012 / 623

On to step 5:
If we divide 4012 by 623, we get 6 and a remainder of 274.
Write down 6 as next digit of the result. 
Result so far: 126.0
Subtracting 3738 from 4012 leaves us with 274.
Fetch the next digit (0) from the dividend, attach it to 274 and continue: 2740 / 623

Moving on to step 6:
The number 623 fits into 2740 4 times, leaving a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 1264.0
If we subtract 2492 from 2740, we get 248.
Bring next digit (3) of the dividend behind the 248 and repeat the process: 2483 / 623

On to step 7:
The number 623 fits into 2483 3 times, leaving a remainder of 614.
The number 3 becomes the next digit in our result. 
Result so far: 12643.0
The remainder is 614 after subtracting 1869 from 2483.
Grab the next digit (4) from the dividend, add it to 614, then carry on: 6144 / 623

On to step 8:
When dividing 6144 by 623, we get 9 with a remainder of 537.
Record the quotient 9 as the next digit in the result. 
Result so far: 126439.0
Deduct 5607 from 6144 and we're left with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Let's proceed to step 9:
623 goes into 5370 8 times with a remainder of 386.
Use 8 as the next digit of our solution. 
Result so far: 126439.8
If we subtract 4984 from 5370, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 10:
If we divide 3860 by 623, we get 6 and a remainder of 122.
Use 6 as the next digit of our solution. 
Result so far: 126439.86
If we subtract 3738 from 3860, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 11:
623 goes into 1220 1 times with a remainder of 597.
Put 1 as the next digit of the answer. 
Result so far: 126439.861
The remainder is 597 after subtracting 623 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Moving on to step 12:
623 goes into 5970 9 times with a remainder of 363.
Record the quotient 9 as the next digit in the result. 
Result so far: 126439.8619
Subtracting 5607 from 5970 leaves us 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 13:
623 can be fit into 3630 5 times, resulting in a remainder of 515.
The next digit of our result is 5. 
Result so far: 126439.86195
The remainder is 515 after subtracting 3115 from 3630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 14:
When dividing 5150 by 623, we get 8 with a remainder of 166.
Put 8 as the next digit of the answer. 
Result so far: 126439.861958
If we subtract 4984 from 5150, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 15:
1660 divided by 623 is 2 with a remainder of 414.
The number 2 becomes the next digit in our result. 
Result so far: 126439.8619582
Subtract 1246 from 1660 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 16:
623 can be fit into 4140 6 times, resulting in a remainder of 402.
Put 6 as the next digit of the answer. 
Result so far: 126439.86195826
If we subtract 3738 from 4140, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

The final result is 126439.86195826 with a remainder of 4.02e-07.
