We're dividing 71778181 by 56 
The aim is to understand the frequency of 56 in 71778181.

On to step 1:
When dividing 7 by 56, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 56

Moving on to step 2:
56 can be fit into 71 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 56 from 71 leaves us with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 56

Moving on to step 3:
The number 56 fits into 157 2 times, leaving a remainder of 45.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 112 from 157, we get 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 56

Step 4:
If we divide 457 by 56, we get 8 and a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 128.0
If we take 448 away from 457, we end up with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 56

Moving on to step 5:
If we divide 98 by 56, we get 1 and a remainder of 42.
The next digit of our result is 1. 
Result so far: 1281.0
Deduct 56 from 98 and we're left with 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 56

Step 6:
When dividing 421 by 56, we get 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 12817.0
Subtract 392 from 421 to get 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 56

Step 7:
If we divide 298 by 56, we get 5 and a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 128175.0
If we subtract 280 from 298, we get 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 56

Going ahead to step 8:
56 goes into 181 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 1281753.0
Subtract 168 from 181 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
The number 56 fits into 130 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 1281753.2
If we take 112 away from 130, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
180 divided by 56 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 1281753.23
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
56 can be fit into 120 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1281753.232
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
When dividing 80 by 56, we get 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1281753.2321
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
240 divided by 56 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 1281753.23214
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
When dividing 160 by 56, we get 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 1281753.232142
Deduct 112 from 160 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 15:
If we divide 480 by 56, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 1281753.2321428
Deduct 448 from 480 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 16:
320 divided by 56 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 1281753.23214285
Deduct 280 from 320 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.

After the division, we end up with 1281753.23214285 and a remainder of 4e-08.
