We look at the division of 19894901 by 926 
The aim is to understand the frequency of 926 in 19894901.

Let's proceed to step 1:
The number 926 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 926

Advancing to step 2:
926 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 926

Going ahead to step 3:
926 goes into 198 0 times with a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 198, we get 198.
Bring next digit (9) of the dividend behind the 198 and repeat the process: 1989 / 926

Advancing to step 4:
1989 divided by 926 is 2 with a remainder of 137.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1852 from 1989, we get 137.
Grab the next digit (4) from the dividend, add it to 137, then carry on: 1374 / 926

Moving on to step 5:
The number 926 fits into 1374 1 times, leaving a remainder of 448.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 926 away from 1374, we end up with 448.
Grab the next digit (9) from the dividend, add it to 448, then carry on: 4489 / 926

Going ahead to step 6:
926 goes into 4489 4 times with a remainder of 785.
Put 4 as the next digit of the answer. 
Result so far: 214.0
The remainder is 785 after subtracting 3704 from 4489.
Bring next digit (0) of the dividend behind the 785 and repeat the process: 7850 / 926

Moving on to step 7:
If we divide 7850 by 926, we get 8 and a remainder of 442.
Record the quotient 8 as the next digit in the result. 
Result so far: 2148.0
If we take 7408 away from 7850, we end up with 442.
Append the next digit (1) from the dividend to 442 and continue with: 4421 / 926

Moving on to step 8:
926 can be fit into 4421 4 times, resulting in a remainder of 717.
Write down 4 as next digit of the result. 
Result so far: 21484.0
If we take 3704 away from 4421, we end up with 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

On to step 9:
When dividing 7170 by 926, we get 7 with a remainder of 688.
Write down 7 as next digit of the result. 
Result so far: 21484.7
Subtract 6482 from 7170 to get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

On to step 10:
926 goes into 6880 7 times with a remainder of 398.
Write down 7 as next digit of the result. 
Result so far: 21484.77
If we subtract 6482 from 6880, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

The quotient of the division is 21484.77, and the remainder is 0.398.
