75476701 ÷ 578 
The aim is to understand the frequency of 578 in 75476701.

Step 1:
578 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 578

Let's proceed to step 2:
If we divide 75 by 578, we get 0 and a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Take the next digit (4) from the dividend and append it to 75, then repeat: 754 / 578

On to step 3:
578 can be fit into 754 1 times, resulting in a remainder of 176.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 578 from 754 and we're left with 176.
Fetch the next digit (7) from the dividend, attach it to 176 and continue: 1767 / 578

Advancing to step 4:
When dividing 1767 by 578, we get 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1734 from 1767 leaves us with 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 578

On to step 5:
The number 578 fits into 336 0 times, leaving a remainder of 336.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
Deduct 0 from 336 and we're left with 336.
Fetch the next digit (7) from the dividend, attach it to 336 and continue: 3367 / 578

On to step 6:
3367 divided by 578 is 5 with a remainder of 477.
Record the quotient 5 as the next digit in the result. 
Result so far: 1305.0
If we take 2890 away from 3367, we end up with 477.
Append the next digit (0) from the dividend to 477 and continue with: 4770 / 578

Advancing to step 7:
578 can be fit into 4770 8 times, resulting in a remainder of 146.
Write down 8 as next digit of the result. 
Result so far: 13058.0
Deduct 4624 from 4770 and we're left with 146.
Bring next digit (1) of the dividend behind the 146 and repeat the process: 1461 / 578

Advancing to step 8:
578 can be fit into 1461 2 times, resulting in a remainder of 305.
Record the quotient 2 as the next digit in the result. 
Result so far: 130582.0
Deduct 1156 from 1461 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 9:
The number 578 fits into 3050 5 times, leaving a remainder of 160.
The number 5 becomes the next digit in our result. 
Result so far: 130582.5
If we subtract 2890 from 3050, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
If we divide 1600 by 578, we get 2 and a remainder of 444.
Write down 2 as next digit of the result. 
Result so far: 130582.52
Subtract 1156 from 1600 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 11:
578 goes into 4440 7 times with a remainder of 394.
Use 7 as the next digit of our solution. 
Result so far: 130582.527
Deduct 4046 from 4440 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 12:
578 can be fit into 3940 6 times, resulting in a remainder of 472.
The next digit of our result is 6. 
Result so far: 130582.5276
Subtracting 3468 from 3940 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 13:
If we divide 4720 by 578, we get 8 and a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 130582.52768
If we take 4624 away from 4720, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 14:
578 can be fit into 960 1 times, resulting in a remainder of 382.
Record the quotient 1 as the next digit in the result. 
Result so far: 130582.527681
Deduct 578 from 960 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 15:
578 can be fit into 3820 6 times, resulting in a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 130582.5276816
If we subtract 3468 from 3820, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 16:
When dividing 3520 by 578, we get 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 130582.52768166
The remainder is 52 after subtracting 3468 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 130582.52768166, with a leftover of 5.2e-08.
