We look at the division of 21222449 by 977 
The aim is to understand the frequency of 977 in 21222449.

Let's proceed to step 1:
When dividing 2 by 977, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 977

Advancing to step 2:
977 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 977

Step 3:
977 can be fit into 212 0 times, resulting in a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 212, we get 212.
Grab the next digit (2) from the dividend, add it to 212, then carry on: 2122 / 977

Going ahead to step 4:
2122 divided by 977 is 2 with a remainder of 168.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1954 from 2122, we get 168.
Grab the next digit (2) from the dividend, add it to 168, then carry on: 1682 / 977

On to step 5:
977 can be fit into 1682 1 times, resulting in a remainder of 705.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 977 away from 1682, we end up with 705.
Take the next digit (4) from the dividend and append it to 705, then repeat: 7054 / 977

Going ahead to step 6:
The number 977 fits into 7054 7 times, leaving a remainder of 215.
Put 7 as the next digit of the answer. 
Result so far: 217.0
If we subtract 6839 from 7054, we get 215.
Include the next digit (4) from the dividend after 215, then repeat: 2154 / 977

Going ahead to step 7:
The number 977 fits into 2154 2 times, leaving a remainder of 200.
Write down 2 as next digit of the result. 
Result so far: 2172.0
If we subtract 1954 from 2154, we get 200.
Fetch the next digit (9) from the dividend, attach it to 200 and continue: 2009 / 977

Let's proceed to step 8:
If we divide 2009 by 977, we get 2 and a remainder of 55.
Put 2 as the next digit of the answer. 
Result so far: 21722.0
Subtract 1954 from 2009 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
977 goes into 550 0 times with a remainder of 550.
The next digit of our result is 0. 
Result so far: 21722.0
Subtract 0 from 550 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 10:
977 can be fit into 5500 5 times, resulting in a remainder of 615.
Use 5 as the next digit of our solution. 
Result so far: 21722.05
Deduct 4885 from 5500 and we're left with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Going ahead to step 11:
When dividing 6150 by 977, we get 6 with a remainder of 288.
The number 6 becomes the next digit in our result. 
Result so far: 21722.056
Deduct 5862 from 6150 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 12:
977 goes into 2880 2 times with a remainder of 926.
Put 2 as the next digit of the answer. 
Result so far: 21722.0562
If we take 1954 away from 2880, we end up with 926.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9260, and continue the process.

Going ahead to step 13:
The number 977 fits into 9260 9 times, leaving a remainder of 467.
Put 9 as the next digit of the answer. 
Result so far: 21722.05629
Deduct 8793 from 9260 and we're left with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Going ahead to step 14:
4670 divided by 977 is 4 with a remainder of 762.
Record the quotient 4 as the next digit in the result. 
Result so far: 21722.056294
Deduct 3908 from 4670 and we're left with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Advancing to step 15:
977 goes into 7620 7 times with a remainder of 781.
Put 7 as the next digit of the answer. 
Result so far: 21722.0562947
If we take 6839 away from 7620, we end up with 781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7810, and continue the process.

Let's proceed to step 16:
The number 977 fits into 7810 7 times, leaving a remainder of 971.
Record the quotient 7 as the next digit in the result. 
Result so far: 21722.05629477
Subtracting 6839 from 7810 leaves us with 971.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9710, and continue the process.

The quotient of the division is 21722.05629477, and the remainder is 9.71e-07.
