Let's divide 39914643 by 689
The aim is to understand the frequency of 689 in 39914643.

Step 1:
If we divide 3 by 689, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 689

Going ahead to step 2:
The number 689 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 689

Step 3:
399 divided by 689 is 0 with a remainder of 399.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 399, we get 399.
Grab the next digit (1) from the dividend, add it to 399, then carry on: 3991 / 689

Going ahead to step 4:
When dividing 3991 by 689, we get 5 with a remainder of 546.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 546 after subtracting 3445 from 3991.
Include the next digit (4) from the dividend after 546, then repeat: 5464 / 689

Going ahead to step 5:
If we divide 5464 by 689, we get 7 and a remainder of 641.
The next digit of our result is 7. 
Result so far: 57.0
Subtracting 4823 from 5464 leaves us with 641.
Include the next digit (6) from the dividend after 641, then repeat: 6416 / 689

Advancing to step 6:
When dividing 6416 by 689, we get 9 with a remainder of 215.
Put 9 as the next digit of the answer. 
Result so far: 579.0
Deduct 6201 from 6416 and we're left with 215.
Include the next digit (4) from the dividend after 215, then repeat: 2154 / 689

On to step 7:
2154 divided by 689 is 3 with a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 5793.0
Subtracting 2067 from 2154 leaves us with 87.
Grab the next digit (3) from the dividend, add it to 87, then carry on: 873 / 689

On to step 8:
689 can be fit into 873 1 times, resulting in a remainder of 184.
Write down 1 as next digit of the result. 
Result so far: 57931.0
If we subtract 689 from 873, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 9:
When dividing 1840 by 689, we get 2 with a remainder of 462.
The number 2 becomes the next digit in our result. 
Result so far: 57931.2
If we subtract 1378 from 1840, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Advancing to step 10:
689 goes into 4620 6 times with a remainder of 486.
The next digit of our result is 6. 
Result so far: 57931.26
Deduct 4134 from 4620 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Advancing to step 11:
689 goes into 4860 7 times with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 57931.267
If we take 4823 away from 4860, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 12:
689 goes into 370 0 times with a remainder of 370.
Record the quotient 0 as the next digit in the result. 
Result so far: 57931.267
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 13:
If we divide 3700 by 689, we get 5 and a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 57931.26705
Subtract 3445 from 3700 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 14:
When dividing 2550 by 689, we get 3 with a remainder of 483.
Record the quotient 3 as the next digit in the result. 
Result so far: 57931.267053
If we take 2067 away from 2550, we end up with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

On to step 15:
4830 divided by 689 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 57931.2670537
Subtracting 4823 from 4830 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 16:
689 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 57931.2670537
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 57931.2670537 with a remaining 7e-08.
