Let's divide 57834430 by 280
The aim is to understand the frequency of 280 in 57834430.

On to step 1:
If we divide 5 by 280, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 280

Step 2:
280 goes into 57 0 times with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 280

Going ahead to step 3:
When dividing 578 by 280, we get 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 560 away from 578, we end up with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 280

Let's proceed to step 4:
When dividing 183 by 280, we get 0 with a remainder of 183.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 183, we end up with 183.
Bring next digit (4) of the dividend behind the 183 and repeat the process: 1834 / 280

Moving on to step 5:
When dividing 1834 by 280, we get 6 with a remainder of 154.
Write down 6 as next digit of the result. 
Result so far: 206.0
If we subtract 1680 from 1834, we get 154.
Grab the next digit (4) from the dividend, add it to 154, then carry on: 1544 / 280

Step 6:
When dividing 1544 by 280, we get 5 with a remainder of 144.
The next digit of our result is 5. 
Result so far: 2065.0
If we take 1400 away from 1544, we end up with 144.
Include the next digit (3) from the dividend after 144, then repeat: 1443 / 280

On to step 7:
When dividing 1443 by 280, we get 5 with a remainder of 43.
Put 5 as the next digit of the answer. 
Result so far: 20655.0
Subtract 1400 from 1443 to get 43.
Append the next digit (0) from the dividend to 43 and continue with: 430 / 280

On to step 8:
430 divided by 280 is 1 with a remainder of 150.
The number 1 becomes the next digit in our result. 
Result so far: 206551.0
If we subtract 280 from 430, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 9:
280 can be fit into 1500 5 times, resulting in a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 206551.5
Deduct 1400 from 1500 and we're left 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.

On to step 10:
280 can be fit into 1000 3 times, resulting in a remainder of 160.
Put 3 as the next digit of the answer. 
Result so far: 206551.53
Subtract 840 from 1000 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
1600 divided by 280 is 5 with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 206551.535
Deduct 1400 from 1600 and we're left with 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 12:
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: 206551.5357
Deduct 1960 from 2000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
When dividing 400 by 280, we get 1 with a remainder of 120.
The next digit of our result is 1. 
Result so far: 206551.53571
Subtracting 280 from 400 leaves us 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.

On to step 14:
If we divide 1200 by 280, we get 4 and a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 206551.535714
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.

Step 15:
When dividing 800 by 280, we get 2 with a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 206551.5357142
If we subtract 560 from 800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 16:
The number 280 fits into 2400 8 times, leaving a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 206551.53571428
Subtract 2240 from 2400 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The quotient of the division is 206551.53571428, and the remainder is 1.6e-07.
