We divide 74643185 by 623
The aim is to understand the frequency of 623 in 74643185.

Going ahead to step 1:
If we divide 7 by 623, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 623

Moving on to step 2:
623 can be fit into 74 0 times, resulting in a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Grab the next digit (6) from the dividend, add it to 74, then carry on: 746 / 623

Going ahead to step 3:
623 can be fit into 746 1 times, resulting in a remainder of 123.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 123 after subtracting 623 from 746.
Include the next digit (4) from the dividend after 123, then repeat: 1234 / 623

Moving on to step 4:
623 can be fit into 1234 1 times, resulting in a remainder of 611.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 623 from 1234 leaves us with 611.
Fetch the next digit (3) from the dividend, attach it to 611 and continue: 6113 / 623

On to step 5:
623 goes into 6113 9 times with a remainder of 506.
The next digit of our result is 9. 
Result so far: 119.0
Deduct 5607 from 6113 and we're left with 506.
Take the next digit (1) from the dividend and append it to 506, then repeat: 5061 / 623

Step 6:
If we divide 5061 by 623, we get 8 and a remainder of 77.
The next digit of our result is 8. 
Result so far: 1198.0
The remainder is 77 after subtracting 4984 from 5061.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 623

Going ahead to step 7:
When dividing 778 by 623, we get 1 with a remainder of 155.
Use 1 as the next digit of our solution. 
Result so far: 11981.0
Subtract 623 from 778 to get 155.
Append the next digit (5) from the dividend to 155 and continue with: 1555 / 623

Moving on to step 8:
1555 divided by 623 is 2 with a remainder of 309.
Record the quotient 2 as the next digit in the result. 
Result so far: 119812.0
If we take 1246 away from 1555, we end up with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Advancing to step 9:
When dividing 3090 by 623, we get 4 with a remainder of 598.
Record the quotient 4 as the next digit in the result. 
Result so far: 119812.4
Deduct 2492 from 3090 and we're left with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Advancing to step 10:
If we divide 5980 by 623, we get 9 and a remainder of 373.
Write down 9 as next digit of the result. 
Result so far: 119812.49
If we subtract 5607 from 5980, we get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 11:
The number 623 fits into 3730 5 times, leaving a remainder of 615.
Put 5 as the next digit of the answer. 
Result so far: 119812.495
Subtract 3115 from 3730 to get 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Going ahead to step 12:
If we divide 6150 by 623, we get 9 and a remainder of 543.
The next digit of our result is 9. 
Result so far: 119812.4959
Subtract 5607 from 6150 to get 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

On to step 13:
When dividing 5430 by 623, we get 8 with a remainder of 446.
Put 8 as the next digit of the answer. 
Result so far: 119812.49598
Deduct 4984 from 5430 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Going ahead to step 14:
623 goes into 4460 7 times with a remainder of 99.
Use 7 as the next digit of our solution. 
Result so far: 119812.495987
If we subtract 4361 from 4460, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 15:
623 goes into 990 1 times with a remainder of 367.
Record the quotient 1 as the next digit in the result. 
Result so far: 119812.4959871
If we take 623 away from 990, we end up with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Advancing to step 16:
623 can be fit into 3670 5 times, resulting in a remainder of 555.
The number 5 becomes the next digit in our result. 
Result so far: 119812.49598715
Subtracting 3115 from 3670 leaves us with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

The final result is 119812.49598715 with a remainder of 5.55e-07.
