86943715 divided by 679 
The aim is to understand the frequency of 679 in 86943715.

Advancing to step 1:
If we divide 8 by 679, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 679

Advancing to step 2:
The number 679 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 679

Step 3:
The number 679 fits into 869 1 times, leaving a remainder of 190.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 679 from 869 to get 190.
Append the next digit (4) from the dividend to 190 and continue with: 1904 / 679

Moving on to step 4:
The number 679 fits into 1904 2 times, leaving a remainder of 546.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 546 after subtracting 1358 from 1904.
Fetch the next digit (3) from the dividend, attach it to 546 and continue: 5463 / 679

Going ahead to step 5:
5463 divided by 679 is 8 with a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtracting 5432 from 5463 leaves us with 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 679

Moving on to step 6:
679 can be fit into 317 0 times, resulting in a remainder of 317.
The next digit of our result is 0. 
Result so far: 1280.0
If we subtract 0 from 317, we get 317.
Grab the next digit (1) from the dividend, add it to 317, then carry on: 3171 / 679

Let's proceed to step 7:
679 goes into 3171 4 times with a remainder of 455.
The next digit of our result is 4. 
Result so far: 12804.0
If we subtract 2716 from 3171, we get 455.
Fetch the next digit (5) from the dividend, attach it to 455 and continue: 4555 / 679

Step 8:
679 goes into 4555 6 times with a remainder of 481.
Write down 6 as next digit of the result. 
Result so far: 128046.0
If we take 4074 away from 4555, we end up with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Step 9:
679 goes into 4810 7 times with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 128046.7
Deduct 4753 from 4810 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 10:
679 goes into 570 0 times with a remainder of 570.
Use 0 as the next digit of our solution. 
Result so far: 128046.7
If we take 0 away from 570, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 11:
679 can be fit into 5700 8 times, resulting in a remainder of 268.
The number 8 becomes the next digit in our result. 
Result so far: 128046.708
The remainder is 268 after subtracting 5432 from 5700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 12:
If we divide 2680 by 679, we get 3 and a remainder of 643.
Put 3 as the next digit of the answer. 
Result so far: 128046.7083
The remainder is 643 after subtracting 2037 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Advancing to step 13:
If we divide 6430 by 679, we get 9 and a remainder of 319.
Write down 9 as next digit of the result. 
Result so far: 128046.70839
Subtracting 6111 from 6430 leaves us with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Going ahead to step 14:
679 can be fit into 3190 4 times, resulting in a remainder of 474.
The number 4 becomes the next digit in our result. 
Result so far: 128046.708394
Subtracting 2716 from 3190 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 15:
If we divide 4740 by 679, we get 6 and a remainder of 666.
Record the quotient 6 as the next digit in the result. 
Result so far: 128046.7083946
Subtract 4074 from 4740 to get 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Moving on to step 16:
679 goes into 6660 9 times with a remainder of 549.
The number 9 becomes the next digit in our result. 
Result so far: 128046.70839469
If we take 6111 away from 6660, we end up with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

The quotient of the division is 128046.70839469, and the remainder is 5.49e-07.
