Let's divide 57622623 by 993
The aim is to understand the frequency of 993 in 57622623.

On to step 1:
When dividing 5 by 993, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 993

Step 2:
57 divided by 993 is 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Fetch the next digit (6) from the dividend, attach it to 57 and continue: 576 / 993

On to step 3:
993 goes into 576 0 times with a remainder of 576.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 576, we get 576.
Grab the next digit (2) from the dividend, add it to 576, then carry on: 5762 / 993

On to step 4:
993 goes into 5762 5 times with a remainder of 797.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 4965 away from 5762, we end up with 797.
Grab the next digit (2) from the dividend, add it to 797, then carry on: 7972 / 993

Moving on to step 5:
993 can be fit into 7972 8 times, resulting in a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Deduct 7944 from 7972 and we're left with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 993

Let's proceed to step 6:
993 can be fit into 286 0 times, resulting in a remainder of 286.
Write down 0 as next digit of the result. 
Result so far: 580.0
Subtract 0 from 286 to get 286.
Append the next digit (2) from the dividend to 286 and continue with: 2862 / 993

Step 7:
993 goes into 2862 2 times with a remainder of 876.
Use 2 as the next digit of our solution. 
Result so far: 5802.0
Deduct 1986 from 2862 and we're left with 876.
Grab the next digit (3) from the dividend, add it to 876, then carry on: 8763 / 993

On to step 8:
The number 993 fits into 8763 8 times, leaving a remainder of 819.
Write down 8 as next digit of the result. 
Result so far: 58028.0
Subtracting 7944 from 8763 leaves us with 819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8190, and continue the process.

On to step 9:
993 goes into 8190 8 times with a remainder of 246.
Write down 8 as next digit of the result. 
Result so far: 58028.8
Subtracting 7944 from 8190 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 10:
The number 993 fits into 2460 2 times, leaving a remainder of 474.
Use 2 as the next digit of our solution. 
Result so far: 58028.82
If we take 1986 away from 2460, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

On to step 11:
When dividing 4740 by 993, we get 4 with a remainder of 768.
Record the quotient 4 as the next digit in the result. 
Result so far: 58028.824
If we subtract 3972 from 4740, we get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Let's proceed to step 12:
When dividing 7680 by 993, we get 7 with a remainder of 729.
Record the quotient 7 as the next digit in the result. 
Result so far: 58028.8247
Deduct 6951 from 7680 and we're left with 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Step 13:
7290 divided by 993 is 7 with a remainder of 339.
Record the quotient 7 as the next digit in the result. 
Result so far: 58028.82477
The remainder is 339 after subtracting 6951 from 7290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

The final outcome is 58028.82477, with a leftover of 0.000339.
