We divide 20911593 by 662
The aim is to understand the frequency of 662 in 20911593.

Advancing to step 1:
The number 662 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 662

Advancing to step 2:
20 divided by 662 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 662

Let's proceed to step 3:
662 goes into 209 0 times with a remainder of 209.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 209 after subtracting 0 from 209.
Include the next digit (1) from the dividend after 209, then repeat: 2091 / 662

Going ahead to step 4:
2091 divided by 662 is 3 with a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 1986 from 2091 to get 105.
Grab the next digit (1) from the dividend, add it to 105, then carry on: 1051 / 662

Advancing to step 5:
If we divide 1051 by 662, we get 1 and a remainder of 389.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 662 away from 1051, we end up with 389.
Append the next digit (5) from the dividend to 389 and continue with: 3895 / 662

Let's proceed to step 6:
662 goes into 3895 5 times with a remainder of 585.
The next digit of our result is 5. 
Result so far: 315.0
If we subtract 3310 from 3895, we get 585.
Bring next digit (9) of the dividend behind the 585 and repeat the process: 5859 / 662

Let's proceed to step 7:
662 can be fit into 5859 8 times, resulting in a remainder of 563.
Use 8 as the next digit of our solution. 
Result so far: 3158.0
Deduct 5296 from 5859 and we're left with 563.
Include the next digit (3) from the dividend after 563, then repeat: 5633 / 662

Step 8:
The number 662 fits into 5633 8 times, leaving a remainder of 337.
Record the quotient 8 as the next digit in the result. 
Result so far: 31588.0
Deduct 5296 from 5633 and we're left with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Advancing to step 9:
The number 662 fits into 3370 5 times, leaving a remainder of 60.
The next digit of our result is 5. 
Result so far: 31588.5
If we take 3310 away from 3370, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
The number 662 fits into 600 0 times, leaving a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 31588.5
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 11:
6000 divided by 662 is 9 with a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 31588.509
Subtract 5958 from 6000 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
The number 662 fits into 420 0 times, leaving a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 31588.509
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 13:
If we divide 4200 by 662, we get 6 and a remainder of 228.
Record the quotient 6 as the next digit in the result. 
Result so far: 31588.50906
If we subtract 3972 from 4200, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 14:
2280 divided by 662 is 3 with a remainder of 294.
Record the quotient 3 as the next digit in the result. 
Result so far: 31588.509063
If we subtract 1986 from 2280, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 15:
662 can be fit into 2940 4 times, resulting in a remainder of 292.
Write down 4 as next digit of the result. 
Result so far: 31588.5090634
Subtract 2648 from 2940 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 16:
If we divide 2920 by 662, we get 4 and a remainder of 272.
The number 4 becomes the next digit in our result. 
Result so far: 31588.50906344
Subtracting 2648 from 2920 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

In conclusion, the division gives 31588.50906344 with a balance of 2.72e-07.
