We look at the division of 54188421 by 334 
The aim is to understand the frequency of 334 in 54188421.

Going ahead to step 1:
If we divide 5 by 334, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 334

Step 2:
When dividing 54 by 334, we get 0 with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 334

Advancing to step 3:
The number 334 fits into 541 1 times, leaving a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 334 from 541, we get 207.
Include the next digit (8) from the dividend after 207, then repeat: 2078 / 334

Going ahead to step 4:
2078 divided by 334 is 6 with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 74 after subtracting 2004 from 2078.
Append the next digit (8) from the dividend to 74 and continue with: 748 / 334

Moving on to step 5:
When dividing 748 by 334, we get 2 with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 162.0
If we subtract 668 from 748, we get 80.
Include the next digit (4) from the dividend after 80, then repeat: 804 / 334

On to step 6:
If we divide 804 by 334, we get 2 and a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 1622.0
Subtract 668 from 804 to get 136.
Bring next digit (2) of the dividend behind the 136 and repeat the process: 1362 / 334

Let's proceed to step 7:
If we divide 1362 by 334, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 16224.0
Subtracting 1336 from 1362 leaves us with 26.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 334

Going ahead to step 8:
The number 334 fits into 261 0 times, leaving a remainder of 261.
Record the quotient 0 as the next digit in the result. 
Result so far: 162240.0
Subtracting 0 from 261 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 9:
334 can be fit into 2610 7 times, resulting in a remainder of 272.
Record the quotient 7 as the next digit in the result. 
Result so far: 162240.7
If we take 2338 away from 2610, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 10:
If we divide 2720 by 334, we get 8 and a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 162240.78
Subtract 2672 from 2720 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
480 divided by 334 is 1 with a remainder of 146.
Put 1 as the next digit of the answer. 
Result so far: 162240.781
If we subtract 334 from 480, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 12:
The number 334 fits into 1460 4 times, leaving a remainder of 124.
Write down 4 as next digit of the result. 
Result so far: 162240.7814
Subtracting 1336 from 1460 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 13:
If we divide 1240 by 334, we get 3 and a remainder of 238.
Put 3 as the next digit of the answer. 
Result so far: 162240.78143
Subtracting 1002 from 1240 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 14:
334 goes into 2380 7 times with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 162240.781437
Subtracting 2338 from 2380 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 15:
If we divide 420 by 334, we get 1 and a remainder of 86.
The next digit of our result is 1. 
Result so far: 162240.7814371
Subtracting 334 from 420 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 16:
334 goes into 860 2 times with a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 162240.78143712
Deduct 668 from 860 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The quotient of the division is 162240.78143712, and the remainder is 1.92e-07.
