We look at the division of 56210981 by 993 
The aim is to understand the frequency of 993 in 56210981.

On to step 1:
The number 993 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 993

Let's proceed to step 2:
If we divide 56 by 993, we get 0 and a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Grab the next digit (2) from the dividend, add it to 56, then carry on: 562 / 993

Let's proceed to step 3:
If we divide 562 by 993, we get 0 and a remainder of 562.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 562, we get 562.
Append the next digit (1) from the dividend to 562 and continue with: 5621 / 993

Advancing to step 4:
993 goes into 5621 5 times with a remainder of 656.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 4965 from 5621 and we're left with 656.
Append the next digit (0) from the dividend to 656 and continue with: 6560 / 993

Let's proceed to step 5:
If we divide 6560 by 993, we get 6 and a remainder of 602.
Write down 6 as next digit of the result. 
Result so far: 56.0
The remainder is 602 after subtracting 5958 from 6560.
Take the next digit (9) from the dividend and append it to 602, then repeat: 6029 / 993

On to step 6:
When dividing 6029 by 993, we get 6 with a remainder of 71.
Write down 6 as next digit of the result. 
Result so far: 566.0
Subtract 5958 from 6029 to get 71.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 993

Step 7:
718 divided by 993 is 0 with a remainder of 718.
The number 0 becomes the next digit in our result. 
Result so far: 5660.0
Subtracting 0 from 718 leaves us with 718.
Grab the next digit (1) from the dividend, add it to 718, then carry on: 7181 / 993

Moving on to step 8:
993 goes into 7181 7 times with a remainder of 230.
The next digit of our result is 7. 
Result so far: 56607.0
If we subtract 6951 from 7181, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 9:
The number 993 fits into 2300 2 times, leaving a remainder of 314.
Put 2 as the next digit of the answer. 
Result so far: 56607.2
The remainder is 314 after subtracting 1986 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 10:
993 goes into 3140 3 times with a remainder of 161.
Write down 3 as next digit of the result. 
Result so far: 56607.23
If we take 2979 away from 3140, we end up with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 11:
1610 divided by 993 is 1 with a remainder of 617.
Put 1 as the next digit of the answer. 
Result so far: 56607.231
If we take 993 away from 1610, we end up with 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Let's proceed to step 12:
When dividing 6170 by 993, we get 6 with a remainder of 212.
Record the quotient 6 as the next digit in the result. 
Result so far: 56607.2316
If we subtract 5958 from 6170, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 13:
When dividing 2120 by 993, we get 2 with a remainder of 134.
Use 2 as the next digit of our solution. 
Result so far: 56607.23162
The remainder is 134 after subtracting 1986 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 14:
1340 divided by 993 is 1 with a remainder of 347.
The next digit of our result is 1. 
Result so far: 56607.231621
If we take 993 away from 1340, we end up with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Let's proceed to step 15:
993 goes into 3470 3 times with a remainder of 491.
Write down 3 as next digit of the result. 
Result so far: 56607.2316213
Subtracting 2979 from 3470 leaves us with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Going ahead to step 16:
993 goes into 4910 4 times with a remainder of 938.
The next digit of our result is 4. 
Result so far: 56607.23162134
If we take 3972 away from 4910, we end up with 938.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9380, and continue the process.

Our division results in 56607.23162134 with a remaining 9.38e-07.
