We're dividing 67539688 by 154 
The aim is to understand the frequency of 154 in 67539688.

On to step 1:
154 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 154

Going ahead to step 2:
When dividing 67 by 154, we get 0 with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 154

On to step 3:
When dividing 675 by 154, we get 4 with a remainder of 59.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 616 from 675, we get 59.
Include the next digit (3) from the dividend after 59, then repeat: 593 / 154

Moving on to step 4:
The number 154 fits into 593 3 times, leaving a remainder of 131.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we take 462 away from 593, we end up with 131.
Include the next digit (9) from the dividend after 131, then repeat: 1319 / 154

Let's proceed to step 5:
When dividing 1319 by 154, we get 8 with a remainder of 87.
Record the quotient 8 as the next digit in the result. 
Result so far: 438.0
Subtract 1232 from 1319 to get 87.
Fetch the next digit (6) from the dividend, attach it to 87 and continue: 876 / 154

Going ahead to step 6:
The number 154 fits into 876 5 times, leaving a remainder of 106.
Use 5 as the next digit of our solution. 
Result so far: 4385.0
The remainder is 106 after subtracting 770 from 876.
Take the next digit (8) from the dividend and append it to 106, then repeat: 1068 / 154

Moving on to step 7:
154 can be fit into 1068 6 times, resulting in a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 43856.0
The remainder is 144 after subtracting 924 from 1068.
Append the next digit (8) from the dividend to 144 and continue with: 1448 / 154

Moving on to step 8:
If we divide 1448 by 154, we get 9 and a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 438569.0
Deduct 1386 from 1448 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
154 goes into 620 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 438569.4
Subtracting 616 from 620 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
When dividing 40 by 154, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 438569.4
Deduct 0 from 40 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.

Advancing to step 11:
When dividing 400 by 154, we get 2 with a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 438569.402
Subtract 308 from 400 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 12:
154 goes into 920 5 times with a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 438569.4025
If we subtract 770 from 920, 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 13:
When dividing 1500 by 154, we get 9 with a remainder of 114.
Write down 9 as next digit of the result. 
Result so far: 438569.40259
If we subtract 1386 from 1500, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 14:
If we divide 1140 by 154, we get 7 and a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 438569.402597
Subtracting 1078 from 1140 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 15:
The number 154 fits into 620 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 438569.4025974
Subtract 616 from 620 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 16:
If we divide 40 by 154, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 438569.4025974
Subtract 0 from 40 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.

After the division, we end up with 438569.4025974 and a remainder of 4e-08.
