Let's divide 71993761 by 623
The aim is to understand the frequency of 623 in 71993761.

On to step 1:
The number 623 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 623

Let's proceed to step 2:
71 divided by 623 is 0 with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Fetch the next digit (9) from the dividend, attach it to 71 and continue: 719 / 623

Let's proceed to step 3:
The number 623 fits into 719 1 times, leaving a remainder of 96.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 623 from 719 to get 96.
Bring next digit (9) of the dividend behind the 96 and repeat the process: 969 / 623

Let's proceed to step 4:
623 goes into 969 1 times with a remainder of 346.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 623 from 969 leaves us with 346.
Fetch the next digit (3) from the dividend, attach it to 346 and continue: 3463 / 623

Moving on to step 5:
623 can be fit into 3463 5 times, resulting in a remainder of 348.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
Subtract 3115 from 3463 to get 348.
Append the next digit (7) from the dividend to 348 and continue with: 3487 / 623

On to step 6:
If we divide 3487 by 623, we get 5 and a remainder of 372.
Use 5 as the next digit of our solution. 
Result so far: 1155.0
Subtracting 3115 from 3487 leaves us with 372.
Fetch the next digit (6) from the dividend, attach it to 372 and continue: 3726 / 623

Step 7:
623 goes into 3726 5 times with a remainder of 611.
Write down 5 as next digit of the result. 
Result so far: 11555.0
Deduct 3115 from 3726 and we're left with 611.
Grab the next digit (1) from the dividend, add it to 611, then carry on: 6111 / 623

Step 8:
623 can be fit into 6111 9 times, resulting in a remainder of 504.
The next digit of our result is 9. 
Result so far: 115559.0
Subtract 5607 from 6111 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 9:
The number 623 fits into 5040 8 times, leaving a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 115559.8
If we take 4984 away from 5040, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
When dividing 560 by 623, we get 0 with a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 115559.8
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 11:
The number 623 fits into 5600 8 times, leaving a remainder of 616.
Write down 8 as next digit of the result. 
Result so far: 115559.808
If we subtract 4984 from 5600, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 12:
If we divide 6160 by 623, we get 9 and a remainder of 553.
Put 9 as the next digit of the answer. 
Result so far: 115559.8089
The remainder is 553 after subtracting 5607 from 6160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Moving on to step 13:
If we divide 5530 by 623, we get 8 and a remainder of 546.
The next digit of our result is 8. 
Result so far: 115559.80898
Subtracting 4984 from 5530 leaves us with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Step 14:
5460 divided by 623 is 8 with a remainder of 476.
Use 8 as the next digit of our solution. 
Result so far: 115559.808988
Subtract 4984 from 5460 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

The quotient of the division is 115559.808988, and the remainder is 4.76e-05.
