79010186 ÷ 635 
The aim is to understand the frequency of 635 in 79010186.

On to step 1:
7 divided by 635 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 635

On to step 2:
635 can be fit into 79 0 times, resulting in a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Append the next digit (0) from the dividend to 79 and continue with: 790 / 635

Going ahead to step 3:
When dividing 790 by 635, we get 1 with a remainder of 155.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 635 from 790, we get 155.
Append the next digit (1) from the dividend to 155 and continue with: 1551 / 635

On to step 4:
635 goes into 1551 2 times with a remainder of 281.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 281 after subtracting 1270 from 1551.
Grab the next digit (0) from the dividend, add it to 281, then carry on: 2810 / 635

Let's proceed to step 5:
When dividing 2810 by 635, we get 4 with a remainder of 270.
Use 4 as the next digit of our solution. 
Result so far: 124.0
If we subtract 2540 from 2810, we get 270.
Grab the next digit (1) from the dividend, add it to 270, then carry on: 2701 / 635

Moving on to step 6:
2701 divided by 635 is 4 with a remainder of 161.
Use 4 as the next digit of our solution. 
Result so far: 1244.0
If we take 2540 away from 2701, we end up with 161.
Bring next digit (8) of the dividend behind the 161 and repeat the process: 1618 / 635

Step 7:
If we divide 1618 by 635, we get 2 and a remainder of 348.
Put 2 as the next digit of the answer. 
Result so far: 12442.0
If we subtract 1270 from 1618, we get 348.
Append the next digit (6) from the dividend to 348 and continue with: 3486 / 635

Advancing to step 8:
When dividing 3486 by 635, we get 5 with a remainder of 311.
The next digit of our result is 5. 
Result so far: 124425.0
Deduct 3175 from 3486 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 9:
635 can be fit into 3110 4 times, resulting in a remainder of 570.
Write down 4 as next digit of the result. 
Result so far: 124425.4
Subtract 2540 from 3110 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 10:
635 can be fit into 5700 8 times, resulting in a remainder of 620.
The number 8 becomes the next digit in our result. 
Result so far: 124425.48
Subtracting 5080 from 5700 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 11:
If we divide 6200 by 635, we get 9 and a remainder of 485.
Write down 9 as next digit of the result. 
Result so far: 124425.489
Subtract 5715 from 6200 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 12:
When dividing 4850 by 635, we get 7 with a remainder of 405.
Put 7 as the next digit of the answer. 
Result so far: 124425.4897
If we take 4445 away from 4850, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 13:
The number 635 fits into 4050 6 times, leaving a remainder of 240.
The number 6 becomes the next digit in our result. 
Result so far: 124425.48976
If we subtract 3810 from 4050, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 14:
When dividing 2400 by 635, we get 3 with a remainder of 495.
The next digit of our result is 3. 
Result so far: 124425.489763
If we take 1905 away from 2400, we end up with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

On to step 15:
If we divide 4950 by 635, we get 7 and a remainder of 505.
Write down 7 as next digit of the result. 
Result so far: 124425.4897637
The remainder is 505 after subtracting 4445 from 4950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Moving on to step 16:
5050 divided by 635 is 7 with a remainder of 605.
Write down 7 as next digit of the result. 
Result so far: 124425.48976377
If we subtract 4445 from 5050, we get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

After the division, we end up with 124425.48976377 and a remainder of 6.05e-07.
