61605426 divided by 548 
The aim is to understand the frequency of 548 in 61605426.

On to step 1:
If we divide 6 by 548, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 548

Step 2:
The number 548 fits into 61 0 times, leaving a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 548

Going ahead to step 3:
When dividing 616 by 548, we get 1 with a remainder of 68.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 548 from 616, we get 68.
Append the next digit (0) from the dividend to 68 and continue with: 680 / 548

Step 4:
If we divide 680 by 548, we get 1 and a remainder of 132.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 548 from 680 and we're left with 132.
Append the next digit (5) from the dividend to 132 and continue with: 1325 / 548

Let's proceed to step 5:
If we divide 1325 by 548, we get 2 and a remainder of 229.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
Deduct 1096 from 1325 and we're left with 229.
Append the next digit (4) from the dividend to 229 and continue with: 2294 / 548

Advancing to step 6:
The number 548 fits into 2294 4 times, leaving a remainder of 102.
Put 4 as the next digit of the answer. 
Result so far: 1124.0
Subtract 2192 from 2294 to get 102.
Grab the next digit (2) from the dividend, add it to 102, then carry on: 1022 / 548

On to step 7:
548 goes into 1022 1 times with a remainder of 474.
Write down 1 as next digit of the result. 
Result so far: 11241.0
Subtracting 548 from 1022 leaves us with 474.
Take the next digit (6) from the dividend and append it to 474, then repeat: 4746 / 548

Going ahead to step 8:
If we divide 4746 by 548, we get 8 and a remainder of 362.
Use 8 as the next digit of our solution. 
Result so far: 112418.0
The remainder is 362 after subtracting 4384 from 4746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 9:
3620 divided by 548 is 6 with a remainder of 332.
Put 6 as the next digit of the answer. 
Result so far: 112418.6
Subtracting 3288 from 3620 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 10:
3320 divided by 548 is 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 112418.66
If we subtract 3288 from 3320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 112418.66 and a remainder of 0.032.
