Let's divide 21444868 by 945
The aim is to understand the frequency of 945 in 21444868.

Let's proceed to step 1:
The number 945 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 945

Let's proceed to step 2:
If we divide 21 by 945, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 945

On to step 3:
The number 945 fits into 214 0 times, leaving a remainder of 214.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 214 after subtracting 0 from 214.
Fetch the next digit (4) from the dividend, attach it to 214 and continue: 2144 / 945

Moving on to step 4:
945 goes into 2144 2 times with a remainder of 254.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 254 after subtracting 1890 from 2144.
Append the next digit (4) from the dividend to 254 and continue with: 2544 / 945

Moving on to step 5:
The number 945 fits into 2544 2 times, leaving a remainder of 654.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 1890 from 2544, we get 654.
Take the next digit (8) from the dividend and append it to 654, then repeat: 6548 / 945

Advancing to step 6:
When dividing 6548 by 945, we get 6 with a remainder of 878.
Put 6 as the next digit of the answer. 
Result so far: 226.0
If we take 5670 away from 6548, we end up with 878.
Append the next digit (6) from the dividend to 878 and continue with: 8786 / 945

Step 7:
When dividing 8786 by 945, we get 9 with a remainder of 281.
Record the quotient 9 as the next digit in the result. 
Result so far: 2269.0
Deduct 8505 from 8786 and we're left with 281.
Append the next digit (8) from the dividend to 281 and continue with: 2818 / 945

Advancing to step 8:
945 goes into 2818 2 times with a remainder of 928.
Put 2 as the next digit of the answer. 
Result so far: 22692.0
If we subtract 1890 from 2818, we get 928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9280, and continue the process.

Moving on to step 9:
If we divide 9280 by 945, we get 9 and a remainder of 775.
Write down 9 as next digit of the result. 
Result so far: 22692.9
Subtract 8505 from 9280 to get 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Advancing to step 10:
7750 divided by 945 is 8 with a remainder of 190.
Write down 8 as next digit of the result. 
Result so far: 22692.98
If we subtract 7560 from 7750, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 11:
945 can be fit into 1900 2 times, resulting in a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 22692.982
If we subtract 1890 from 1900, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
When dividing 100 by 945, we get 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 22692.982
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
945 goes into 1000 1 times with a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 22692.98201
The remainder is 55 after subtracting 945 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 14:
945 can be fit into 550 0 times, resulting in a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 22692.98201
Subtracting 0 from 550 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 15:
When dividing 5500 by 945, we get 5 with a remainder of 775.
Use 5 as the next digit of our solution. 
Result so far: 22692.9820105
The remainder is 775 after subtracting 4725 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

On to step 16:
When dividing 7750 by 945, we get 8 with a remainder of 190.
Record the quotient 8 as the next digit in the result. 
Result so far: 22692.98201058
If we subtract 7560 from 7750, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final outcome is 22692.98201058, with a leftover of 1.9e-07.
