We look at the division of 71684850 by 993 
The aim is to understand the frequency of 993 in 71684850.

Let's proceed to step 1:
When dividing 7 by 993, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 993

On to step 2:
If we divide 71 by 993, we get 0 and a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Fetch the next digit (6) from the dividend, attach it to 71 and continue: 716 / 993

On to step 3:
993 can be fit into 716 0 times, resulting in a remainder of 716.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 716 and we're left with 716.
Take the next digit (8) from the dividend and append it to 716, then repeat: 7168 / 993

Step 4:
The number 993 fits into 7168 7 times, leaving a remainder of 217.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 6951 away from 7168, we end up with 217.
Grab the next digit (4) from the dividend, add it to 217, then carry on: 2174 / 993

Let's proceed to step 5:
2174 divided by 993 is 2 with a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we take 1986 away from 2174, we end up with 188.
Bring next digit (8) of the dividend behind the 188 and repeat the process: 1888 / 993

On to step 6:
If we divide 1888 by 993, we get 1 and a remainder of 895.
The next digit of our result is 1. 
Result so far: 721.0
Subtracting 993 from 1888 leaves us with 895.
Include the next digit (5) from the dividend after 895, then repeat: 8955 / 993

Advancing to step 7:
8955 divided by 993 is 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 7219.0
The remainder is 18 after subtracting 8937 from 8955.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 993

On to step 8:
993 goes into 180 0 times with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 72190.0
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 9:
The number 993 fits into 1800 1 times, leaving a remainder of 807.
Write down 1 as next digit of the result. 
Result so far: 72190.1
The remainder is 807 after subtracting 993 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8070, and continue the process.

On to step 10:
When dividing 8070 by 993, we get 8 with a remainder of 126.
Record the quotient 8 as the next digit in the result. 
Result so far: 72190.18
If we subtract 7944 from 8070, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 11:
If we divide 1260 by 993, we get 1 and a remainder of 267.
Put 1 as the next digit of the answer. 
Result so far: 72190.181
Subtract 993 from 1260 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Going ahead to step 12:
When dividing 2670 by 993, we get 2 with a remainder of 684.
The next digit of our result is 2. 
Result so far: 72190.1812
If we take 1986 away from 2670, we end up with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

On to step 13:
The number 993 fits into 6840 6 times, leaving a remainder of 882.
The next digit of our result is 6. 
Result so far: 72190.18126
Deduct 5958 from 6840 and we're left with 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

Advancing to step 14:
8820 divided by 993 is 8 with a remainder of 876.
Put 8 as the next digit of the answer. 
Result so far: 72190.181268
The remainder is 876 after subtracting 7944 from 8820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

Advancing to step 15:
8760 divided by 993 is 8 with a remainder of 816.
The next digit of our result is 8. 
Result so far: 72190.1812688
The remainder is 816 after subtracting 7944 from 8760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

The quotient of the division is 72190.1812688, and the remainder is 8.16e-06.
