We divide 637769 by 86
The aim is to understand the frequency of 86 in 637769.

Let's proceed to step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 86

On to step 2:
86 can be fit into 63 0 times, resulting in a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Include the next digit (7) from the dividend after 63, then repeat: 637 / 86

Going ahead to step 3:
637 divided by 86 is 7 with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 602 from 637 and we're left with 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 86

Advancing to step 4:
86 goes into 357 4 times with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 74.0
If we subtract 344 from 357, we get 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 86

Advancing to step 5:
136 divided by 86 is 1 with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 741.0
Deduct 86 from 136 and we're left with 50.
Grab the next digit (9) from the dividend, add it to 50, then carry on: 509 / 86

On to step 6:
The number 86 fits into 509 5 times, leaving a remainder of 79.
The next digit of our result is 5. 
Result so far: 7415.0
If we subtract 430 from 509, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 7:
The number 86 fits into 790 9 times, leaving a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 7415.9
Subtracting 774 from 790 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
86 can be fit into 160 1 times, resulting in a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 7415.91
Deduct 86 from 160 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 9:
When dividing 740 by 86, we get 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 7415.918
Subtracting 688 from 740 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
If we divide 520 by 86, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 7415.9186
Deduct 516 from 520 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
86 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 7415.9186
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
86 goes into 400 4 times with a remainder of 56.
The next digit of our result is 4. 
Result so far: 7415.918604
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
If we divide 560 by 86, we get 6 and a remainder of 44.
The next digit of our result is 6. 
Result so far: 7415.9186046
Subtracting 516 from 560 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
The number 86 fits into 440 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 7415.91860465
If we subtract 430 from 440, 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.

The quotient of the division is 7415.91860465, and the remainder is 1e-08.
