We divide 20687945 by 743
The aim is to understand the frequency of 743 in 20687945.

Step 1:
743 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 743

Let's proceed to step 2:
20 divided by 743 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 743

Advancing to step 3:
206 divided by 743 is 0 with a remainder of 206.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 206 and we're left with 206.
Include the next digit (8) from the dividend after 206, then repeat: 2068 / 743

Going ahead to step 4:
743 goes into 2068 2 times with a remainder of 582.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1486 from 2068, we get 582.
Bring next digit (7) of the dividend behind the 582 and repeat the process: 5827 / 743

Going ahead to step 5:
When dividing 5827 by 743, we get 7 with a remainder of 626.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtract 5201 from 5827 to get 626.
Grab the next digit (9) from the dividend, add it to 626, then carry on: 6269 / 743

Let's proceed to step 6:
When dividing 6269 by 743, we get 8 with a remainder of 325.
The next digit of our result is 8. 
Result so far: 278.0
Subtract 5944 from 6269 to get 325.
Fetch the next digit (4) from the dividend, attach it to 325 and continue: 3254 / 743

Step 7:
743 can be fit into 3254 4 times, resulting in a remainder of 282.
Use 4 as the next digit of our solution. 
Result so far: 2784.0
Deduct 2972 from 3254 and we're left with 282.
Bring next digit (5) of the dividend behind the 282 and repeat the process: 2825 / 743

Let's proceed to step 8:
2825 divided by 743 is 3 with a remainder of 596.
Use 3 as the next digit of our solution. 
Result so far: 27843.0
Deduct 2229 from 2825 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 9:
If we divide 5960 by 743, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 27843.8
If we subtract 5944 from 5960, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
If we divide 160 by 743, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 27843.8
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 11:
When dividing 1600 by 743, we get 2 with a remainder of 114.
Record the quotient 2 as the next digit in the result. 
Result so far: 27843.802
Subtracting 1486 from 1600 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 12:
1140 divided by 743 is 1 with a remainder of 397.
Record the quotient 1 as the next digit in the result. 
Result so far: 27843.8021
If we take 743 away from 1140, we end up with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

On to step 13:
If we divide 3970 by 743, we get 5 and a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 27843.80215
The remainder is 255 after subtracting 3715 from 3970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 14:
743 goes into 2550 3 times with a remainder of 321.
Use 3 as the next digit of our solution. 
Result so far: 27843.802153
Subtracting 2229 from 2550 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Advancing to step 15:
743 can be fit into 3210 4 times, resulting in a remainder of 238.
Record the quotient 4 as the next digit in the result. 
Result so far: 27843.8021534
The remainder is 238 after subtracting 2972 from 3210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 16:
743 can be fit into 2380 3 times, resulting in a remainder of 151.
The next digit of our result is 3. 
Result so far: 27843.80215343
The remainder is 151 after subtracting 2229 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

The final outcome is 27843.80215343, with a leftover of 1.51e-07.
