63420007 ÷ 578 
The aim is to understand the frequency of 578 in 63420007.

Step 1:
578 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 578

Advancing to step 2:
63 divided by 578 is 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 578

Going ahead to step 3:
If we divide 634 by 578, we get 1 and a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 578 from 634 to get 56.
Fetch the next digit (2) from the dividend, attach it to 56 and continue: 562 / 578

Advancing to step 4:
The number 578 fits into 562 0 times, leaving a remainder of 562.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 562 after subtracting 0 from 562.
Fetch the next digit (0) from the dividend, attach it to 562 and continue: 5620 / 578

On to step 5:
When dividing 5620 by 578, we get 9 with a remainder of 418.
Write down 9 as next digit of the result. 
Result so far: 109.0
Deduct 5202 from 5620 and we're left with 418.
Bring next digit (0) of the dividend behind the 418 and repeat the process: 4180 / 578

Step 6:
If we divide 4180 by 578, we get 7 and a remainder of 134.
The next digit of our result is 7. 
Result so far: 1097.0
Subtract 4046 from 4180 to get 134.
Grab the next digit (0) from the dividend, add it to 134, then carry on: 1340 / 578

Step 7:
578 can be fit into 1340 2 times, resulting in a remainder of 184.
Write down 2 as next digit of the result. 
Result so far: 10972.0
Subtracting 1156 from 1340 leaves us with 184.
Append the next digit (7) from the dividend to 184 and continue with: 1847 / 578

Going ahead to step 8:
1847 divided by 578 is 3 with a remainder of 113.
The number 3 becomes the next digit in our result. 
Result so far: 109723.0
Subtracting 1734 from 1847 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 9:
578 can be fit into 1130 1 times, resulting in a remainder of 552.
Write down 1 as next digit of the result. 
Result so far: 109723.1
Subtract 578 from 1130 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 10:
When dividing 5520 by 578, we get 9 with a remainder of 318.
Put 9 as the next digit of the answer. 
Result so far: 109723.19
If we take 5202 away from 5520, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 11:
The number 578 fits into 3180 5 times, leaving a remainder of 290.
Write down 5 as next digit of the result. 
Result so far: 109723.195
Subtract 2890 from 3180 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 12:
If we divide 2900 by 578, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 109723.1955
If we subtract 2890 from 2900, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 109723.1955 with a remaining 0.0001.
