13890502 divided by 677 
The aim is to understand the frequency of 677 in 13890502.

Advancing to step 1:
1 divided by 677 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 677

On to step 2:
13 divided by 677 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 677

Moving on to step 3:
677 goes into 138 0 times with a remainder of 138.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 138 leaves us with 138.
Take the next digit (9) from the dividend and append it to 138, then repeat: 1389 / 677

Going ahead to step 4:
The number 677 fits into 1389 2 times, leaving a remainder of 35.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1354 from 1389, we get 35.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 677

Advancing to step 5:
If we divide 350 by 677, we get 0 and a remainder of 350.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 350 after subtracting 0 from 350.
Grab the next digit (5) from the dividend, add it to 350, then carry on: 3505 / 677

Going ahead to step 6:
If we divide 3505 by 677, we get 5 and a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 205.0
Subtracting 3385 from 3505 leaves us with 120.
Grab the next digit (0) from the dividend, add it to 120, then carry on: 1200 / 677

Advancing to step 7:
1200 divided by 677 is 1 with a remainder of 523.
The next digit of our result is 1. 
Result so far: 2051.0
If we subtract 677 from 1200, we get 523.
Fetch the next digit (2) from the dividend, attach it to 523 and continue: 5232 / 677

Going ahead to step 8:
The number 677 fits into 5232 7 times, leaving a remainder of 493.
The next digit of our result is 7. 
Result so far: 20517.0
If we subtract 4739 from 5232, we get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Step 9:
677 can be fit into 4930 7 times, resulting in a remainder of 191.
Write down 7 as next digit of the result. 
Result so far: 20517.7
Deduct 4739 from 4930 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 10:
1910 divided by 677 is 2 with a remainder of 556.
The next digit of our result is 2. 
Result so far: 20517.72
Subtract 1354 from 1910 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Going ahead to step 11:
677 can be fit into 5560 8 times, resulting in a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 20517.728
If we take 5416 away from 5560, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 12:
677 can be fit into 1440 2 times, resulting in a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 20517.7282
If we subtract 1354 from 1440, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 13:
The number 677 fits into 860 1 times, leaving a remainder of 183.
Write down 1 as next digit of the result. 
Result so far: 20517.72821
Deduct 677 from 860 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Going ahead to step 14:
The number 677 fits into 1830 2 times, leaving a remainder of 476.
Write down 2 as next digit of the result. 
Result so far: 20517.728212
The remainder is 476 after subtracting 1354 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 15:
4760 divided by 677 is 7 with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 20517.7282127
Subtract 4739 from 4760 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 16:
677 can be fit into 210 0 times, resulting in a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 20517.7282127
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 20517.7282127, with a leftover of 2.1e-07.
