34109363 ÷ 280 
The aim is to understand the frequency of 280 in 34109363.

On to step 1:
The number 280 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 280

Advancing to step 2:
If we divide 34 by 280, we get 0 and a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 280

Let's proceed to step 3:
280 can be fit into 341 1 times, resulting in a remainder of 61.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 280 from 341 and we're left with 61.
Bring next digit (0) of the dividend behind the 61 and repeat the process: 610 / 280

Advancing to step 4:
280 goes into 610 2 times with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 560 from 610 to get 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 280

Moving on to step 5:
When dividing 509 by 280, we get 1 with a remainder of 229.
The next digit of our result is 1. 
Result so far: 121.0
If we take 280 away from 509, we end up with 229.
Append the next digit (3) from the dividend to 229 and continue with: 2293 / 280

Moving on to step 6:
When dividing 2293 by 280, we get 8 with a remainder of 53.
Use 8 as the next digit of our solution. 
Result so far: 1218.0
Deduct 2240 from 2293 and we're left with 53.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 280

Advancing to step 7:
280 goes into 536 1 times with a remainder of 256.
The number 1 becomes the next digit in our result. 
Result so far: 12181.0
Subtract 280 from 536 to get 256.
Grab the next digit (3) from the dividend, add it to 256, then carry on: 2563 / 280

Step 8:
2563 divided by 280 is 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 121819.0
If we subtract 2520 from 2563, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 9:
When dividing 430 by 280, we get 1 with a remainder of 150.
Put 1 as the next digit of the answer. 
Result so far: 121819.1
Deduct 280 from 430 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
If we divide 1500 by 280, we get 5 and a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 121819.15
If we take 1400 away from 1500, we end up with 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 11:
The number 280 fits into 1000 3 times, leaving a remainder of 160.
Put 3 as the next digit of the answer. 
Result so far: 121819.153
Subtracting 840 from 1000 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 12:
When dividing 1600 by 280, we get 5 with a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 121819.1535
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.

On to step 13:
The number 280 fits into 2000 7 times, leaving a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 121819.15357
Subtract 1960 from 2000 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
280 can be fit into 400 1 times, resulting in a remainder of 120.
The next digit of our result is 1. 
Result so far: 121819.153571
If we subtract 280 from 400, we get 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 15:
280 goes into 1200 4 times with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 121819.1535714
If we take 1120 away from 1200, we end up 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.

On to step 16:
If we divide 800 by 280, we get 2 and a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 121819.15357142
Subtracting 560 from 800 leaves us 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.

After the division, we end up with 121819.15357142 and a remainder of 2.4e-07.
