We're dividing 70360378 by 863 
The aim is to understand the frequency of 863 in 70360378.

Advancing to step 1:
If we divide 7 by 863, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 863

Advancing to step 2:
70 divided by 863 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 863

Step 3:
863 can be fit into 703 0 times, resulting in a remainder of 703.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 703 to get 703.
Grab the next digit (6) from the dividend, add it to 703, then carry on: 7036 / 863

Let's proceed to step 4:
If we divide 7036 by 863, we get 8 and a remainder of 132.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6904 away from 7036, we end up with 132.
Take the next digit (0) from the dividend and append it to 132, then repeat: 1320 / 863

Moving on to step 5:
The number 863 fits into 1320 1 times, leaving a remainder of 457.
The next digit of our result is 1. 
Result so far: 81.0
Subtracting 863 from 1320 leaves us with 457.
Grab the next digit (3) from the dividend, add it to 457, then carry on: 4573 / 863

On to step 6:
863 can be fit into 4573 5 times, resulting in a remainder of 258.
Use 5 as the next digit of our solution. 
Result so far: 815.0
Subtracting 4315 from 4573 leaves us with 258.
Bring next digit (7) of the dividend behind the 258 and repeat the process: 2587 / 863

On to step 7:
2587 divided by 863 is 2 with a remainder of 861.
Record the quotient 2 as the next digit in the result. 
Result so far: 8152.0
The remainder is 861 after subtracting 1726 from 2587.
Take the next digit (8) from the dividend and append it to 861, then repeat: 8618 / 863

Going ahead to step 8:
8618 divided by 863 is 9 with a remainder of 851.
The next digit of our result is 9. 
Result so far: 81529.0
Subtract 7767 from 8618 to get 851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

Let's proceed to step 9:
863 can be fit into 8510 9 times, resulting in a remainder of 743.
Record the quotient 9 as the next digit in the result. 
Result so far: 81529.9
Subtract 7767 from 8510 to get 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Step 10:
863 can be fit into 7430 8 times, resulting in a remainder of 526.
Use 8 as the next digit of our solution. 
Result so far: 81529.98
Subtracting 6904 from 7430 leaves us with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Advancing to step 11:
5260 divided by 863 is 6 with a remainder of 82.
The next digit of our result is 6. 
Result so far: 81529.986
Deduct 5178 from 5260 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 12:
When dividing 820 by 863, we get 0 with a remainder of 820.
Use 0 as the next digit of our solution. 
Result so far: 81529.986
If we take 0 away from 820, we end up with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

On to step 13:
863 can be fit into 8200 9 times, resulting in a remainder of 433.
Record the quotient 9 as the next digit in the result. 
Result so far: 81529.98609
If we take 7767 away from 8200, we end up with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 14:
863 can be fit into 4330 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 81529.986095
Deduct 4315 from 4330 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 15:
When dividing 150 by 863, we get 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 81529.986095
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 16:
863 can be fit into 1500 1 times, resulting in a remainder of 637.
Record the quotient 1 as the next digit in the result. 
Result so far: 81529.98609501
Deduct 863 from 1500 and we're left with 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

The final result is 81529.98609501 with a remainder of 6.37e-07.
