We look at the division of 13861837 by 705 
The aim is to understand the frequency of 705 in 13861837.

On to step 1:
705 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 705

Let's proceed to step 2:
The number 705 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 705

On to step 3:
When dividing 138 by 705, we get 0 with a remainder of 138.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 138 after subtracting 0 from 138.
Take the next digit (6) from the dividend and append it to 138, then repeat: 1386 / 705

Advancing to step 4:
705 goes into 1386 1 times with a remainder of 681.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 705 away from 1386, we end up with 681.
Take the next digit (1) from the dividend and append it to 681, then repeat: 6811 / 705

On to step 5:
When dividing 6811 by 705, we get 9 with a remainder of 466.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 466 after subtracting 6345 from 6811.
Include the next digit (8) from the dividend after 466, then repeat: 4668 / 705

Let's proceed to step 6:
When dividing 4668 by 705, we get 6 with a remainder of 438.
The number 6 becomes the next digit in our result. 
Result so far: 196.0
Subtract 4230 from 4668 to get 438.
Bring next digit (3) of the dividend behind the 438 and repeat the process: 4383 / 705

Advancing to step 7:
705 goes into 4383 6 times with a remainder of 153.
Put 6 as the next digit of the answer. 
Result so far: 1966.0
Subtracting 4230 from 4383 leaves us with 153.
Append the next digit (7) from the dividend to 153 and continue with: 1537 / 705

Going ahead to step 8:
705 can be fit into 1537 2 times, resulting in a remainder of 127.
The next digit of our result is 2. 
Result so far: 19662.0
If we take 1410 away from 1537, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 9:
If we divide 1270 by 705, we get 1 and a remainder of 565.
Write down 1 as next digit of the result. 
Result so far: 19662.1
Deduct 705 from 1270 and we're left with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Advancing to step 10:
705 goes into 5650 8 times with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 19662.18
Subtracting 5640 from 5650 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
705 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 19662.18
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
705 can be fit into 1000 1 times, resulting in a remainder of 295.
The number 1 becomes the next digit in our result. 
Result so far: 19662.1801
Subtracting 705 from 1000 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 13:
705 can be fit into 2950 4 times, resulting in a remainder of 130.
Use 4 as the next digit of our solution. 
Result so far: 19662.18014
The remainder is 130 after subtracting 2820 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 14:
The number 705 fits into 1300 1 times, leaving a remainder of 595.
Use 1 as the next digit of our solution. 
Result so far: 19662.180141
If we subtract 705 from 1300, we get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Going ahead to step 15:
705 goes into 5950 8 times with a remainder of 310.
Write down 8 as next digit of the result. 
Result so far: 19662.1801418
If we take 5640 away from 5950, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 16:
3100 divided by 705 is 4 with a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 19662.18014184
The remainder is 280 after subtracting 2820 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 19662.18014184 and a remainder of 2.8e-07.
