We're dividing 51581755 by 340 
The aim is to understand the frequency of 340 in 51581755.

Going ahead to step 1:
If we divide 5 by 340, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 340

Step 2:
The number 340 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 340

Let's proceed to step 3:
If we divide 515 by 340, we get 1 and a remainder of 175.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 340 from 515 leaves us with 175.
Include the next digit (8) from the dividend after 175, then repeat: 1758 / 340

Let's proceed to step 4:
1758 divided by 340 is 5 with a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 1700 from 1758, we get 58.
Grab the next digit (1) from the dividend, add it to 58, then carry on: 581 / 340

Going ahead to step 5:
340 can be fit into 581 1 times, resulting in a remainder of 241.
The next digit of our result is 1. 
Result so far: 151.0
If we take 340 away from 581, we end up with 241.
Take the next digit (7) from the dividend and append it to 241, then repeat: 2417 / 340

Step 6:
340 goes into 2417 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 1517.0
If we take 2380 away from 2417, we end up with 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 340

Going ahead to step 7:
340 can be fit into 375 1 times, resulting in a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 15171.0
The remainder is 35 after subtracting 340 from 375.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 340

Let's proceed to step 8:
When dividing 355 by 340, we get 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 151711.0
Subtract 340 from 355 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
340 can be fit into 150 0 times, resulting in a remainder of 150.
The next digit of our result is 0. 
Result so far: 151711.0
Subtracting 0 from 150 leaves us 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.

Moving on to step 10:
1500 divided by 340 is 4 with a remainder of 140.
The next digit of our result is 4. 
Result so far: 151711.04
The remainder is 140 after subtracting 1360 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
340 goes into 1400 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 151711.044
The remainder is 40 after subtracting 1360 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 151711.044, and the remainder is 0.004.
