We're dividing 70148672 by 689 
The aim is to understand the frequency of 689 in 70148672.

Going ahead to step 1:
When dividing 7 by 689, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 689

Going ahead to step 2:
689 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Take the next digit (1) from the dividend and append it to 70, then repeat: 701 / 689

Going ahead to step 3:
689 can be fit into 701 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 689 away from 701, we end up with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 689

Advancing to step 4:
The number 689 fits into 124 0 times, leaving a remainder of 124.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 124, we end up with 124.
Take the next digit (8) from the dividend and append it to 124, then repeat: 1248 / 689

Going ahead to step 5:
1248 divided by 689 is 1 with a remainder of 559.
Use 1 as the next digit of our solution. 
Result so far: 101.0
The remainder is 559 after subtracting 689 from 1248.
Take the next digit (6) from the dividend and append it to 559, then repeat: 5596 / 689

Moving on to step 6:
When dividing 5596 by 689, we get 8 with a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 1018.0
The remainder is 84 after subtracting 5512 from 5596.
Grab the next digit (7) from the dividend, add it to 84, then carry on: 847 / 689

Advancing to step 7:
847 divided by 689 is 1 with a remainder of 158.
The next digit of our result is 1. 
Result so far: 10181.0
If we take 689 away from 847, we end up with 158.
Grab the next digit (2) from the dividend, add it to 158, then carry on: 1582 / 689

Step 8:
689 goes into 1582 2 times with a remainder of 204.
Write down 2 as next digit of the result. 
Result so far: 101812.0
If we take 1378 away from 1582, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 9:
If we divide 2040 by 689, we get 2 and a remainder of 662.
The number 2 becomes the next digit in our result. 
Result so far: 101812.2
If we subtract 1378 from 2040, we get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Going ahead to step 10:
If we divide 6620 by 689, we get 9 and a remainder of 419.
Record the quotient 9 as the next digit in the result. 
Result so far: 101812.29
Subtract 6201 from 6620 to get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Let's proceed to step 11:
689 can be fit into 4190 6 times, resulting in a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 101812.296
If we take 4134 away from 4190, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
689 goes into 560 0 times with a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 101812.296
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 13:
If we divide 5600 by 689, we get 8 and a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 101812.29608
Subtracting 5512 from 5600 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 14:
If we divide 880 by 689, we get 1 and a remainder of 191.
Use 1 as the next digit of our solution. 
Result so far: 101812.296081
Deduct 689 from 880 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.

Let's proceed to step 15:
689 goes into 1910 2 times with a remainder of 532.
Put 2 as the next digit of the answer. 
Result so far: 101812.2960812
If we subtract 1378 from 1910, we get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Step 16:
5320 divided by 689 is 7 with a remainder of 497.
The number 7 becomes the next digit in our result. 
Result so far: 101812.29608127
If we take 4823 away from 5320, we end up with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

The final outcome is 101812.29608127, with a leftover of 4.97e-07.
