59998323 ÷ 678 
The aim is to understand the frequency of 678 in 59998323.

Moving on to step 1:
678 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 678

On to step 2:
The number 678 fits into 59 0 times, leaving a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 59 after subtracting 0 from 59.
Grab the next digit (9) from the dividend, add it to 59, then carry on: 599 / 678

Going ahead to step 3:
When dividing 599 by 678, we get 0 with a remainder of 599.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 599 leaves us with 599.
Append the next digit (9) from the dividend to 599 and continue with: 5999 / 678

Moving on to step 4:
When dividing 5999 by 678, we get 8 with a remainder of 575.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 5424 away from 5999, we end up with 575.
Append the next digit (8) from the dividend to 575 and continue with: 5758 / 678

Advancing to step 5:
When dividing 5758 by 678, we get 8 with a remainder of 334.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Deduct 5424 from 5758 and we're left with 334.
Bring next digit (3) of the dividend behind the 334 and repeat the process: 3343 / 678

Going ahead to step 6:
When dividing 3343 by 678, we get 4 with a remainder of 631.
Write down 4 as next digit of the result. 
Result so far: 884.0
If we subtract 2712 from 3343, we get 631.
Include the next digit (2) from the dividend after 631, then repeat: 6312 / 678

On to step 7:
678 goes into 6312 9 times with a remainder of 210.
The number 9 becomes the next digit in our result. 
Result so far: 8849.0
If we subtract 6102 from 6312, we get 210.
Take the next digit (3) from the dividend and append it to 210, then repeat: 2103 / 678

Advancing to step 8:
678 can be fit into 2103 3 times, resulting in a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 88493.0
If we subtract 2034 from 2103, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
The number 678 fits into 690 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 88493.1
Deduct 678 from 690 and we're left 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.

Going ahead to step 10:
120 divided by 678 is 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 88493.1
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
1200 divided by 678 is 1 with a remainder of 522.
Record the quotient 1 as the next digit in the result. 
Result so far: 88493.101
Subtract 678 from 1200 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

On to step 12:
When dividing 5220 by 678, we get 7 with a remainder of 474.
Write down 7 as next digit of the result. 
Result so far: 88493.1017
If we subtract 4746 from 5220, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 13:
678 can be fit into 4740 6 times, resulting in a remainder of 672.
Use 6 as the next digit of our solution. 
Result so far: 88493.10176
If we take 4068 away from 4740, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Moving on to step 14:
If we divide 6720 by 678, we get 9 and a remainder of 618.
Put 9 as the next digit of the answer. 
Result so far: 88493.101769
If we subtract 6102 from 6720, we get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Going ahead to step 15:
When dividing 6180 by 678, we get 9 with a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 88493.1017699
If we subtract 6102 from 6180, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

After the division, we end up with 88493.1017699 and a remainder of 7.8e-07.
