We're dividing 59604621 by 280 
The aim is to understand the frequency of 280 in 59604621.

Moving on to step 1:
The number 280 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 280

Advancing to step 2:
The number 280 fits into 59 0 times, leaving a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 59 leaves us with 59.
Take the next digit (6) from the dividend and append it to 59, then repeat: 596 / 280

Advancing to step 3:
The number 280 fits into 596 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 560 from 596, we get 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 280

Going ahead to step 4:
If we divide 360 by 280, we get 1 and a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 80 after subtracting 280 from 360.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 280

Going ahead to step 5:
When dividing 804 by 280, we get 2 with a remainder of 244.
Write down 2 as next digit of the result. 
Result so far: 212.0
If we subtract 560 from 804, we get 244.
Take the next digit (6) from the dividend and append it to 244, then repeat: 2446 / 280

Let's proceed to step 6:
When dividing 2446 by 280, we get 8 with a remainder of 206.
Record the quotient 8 as the next digit in the result. 
Result so far: 2128.0
If we subtract 2240 from 2446, we get 206.
Append the next digit (2) from the dividend to 206 and continue with: 2062 / 280

On to step 7:
If we divide 2062 by 280, we get 7 and a remainder of 102.
Put 7 as the next digit of the answer. 
Result so far: 21287.0
If we take 1960 away from 2062, we end up with 102.
Include the next digit (1) from the dividend after 102, then repeat: 1021 / 280

Let's proceed to step 8:
280 can be fit into 1021 3 times, resulting in a remainder of 181.
The number 3 becomes the next digit in our result. 
Result so far: 212873.0
Subtracting 840 from 1021 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 9:
The number 280 fits into 1810 6 times, leaving a remainder of 130.
Use 6 as the next digit of our solution. 
Result so far: 212873.6
If we take 1680 away from 1810, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
280 can be fit into 1300 4 times, resulting in a remainder of 180.
Record the quotient 4 as the next digit in the result. 
Result so far: 212873.64
Subtract 1120 from 1300 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
The number 280 fits into 1800 6 times, leaving a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 212873.646
Deduct 1680 from 1800 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 12:
If we divide 1200 by 280, we get 4 and a remainder of 80.
The next digit of our result is 4. 
Result so far: 212873.6464
Deduct 1120 from 1200 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
280 goes into 800 2 times with a remainder of 240.
The next digit of our result is 2. 
Result so far: 212873.64642
If we take 560 away from 800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 14:
2400 divided by 280 is 8 with a remainder of 160.
Put 8 as the next digit of the answer. 
Result so far: 212873.646428
The remainder is 160 after subtracting 2240 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
The number 280 fits into 1600 5 times, leaving a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 212873.6464285
If we subtract 1400 from 1600, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 16:
280 can be fit into 2000 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 212873.64642857
The remainder is 40 after subtracting 1960 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 212873.64642857, with a leftover of 4e-08.
