89190194 divided by 690 
The aim is to understand the frequency of 690 in 89190194.

Advancing to step 1:
When dividing 8 by 690, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 690

Let's proceed to step 2:
When dividing 89 by 690, we get 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Bring next digit (1) of the dividend behind the 89 and repeat the process: 891 / 690

Going ahead to step 3:
The number 690 fits into 891 1 times, leaving a remainder of 201.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 690 from 891 and we're left with 201.
Fetch the next digit (9) from the dividend, attach it to 201 and continue: 2019 / 690

Going ahead to step 4:
If we divide 2019 by 690, we get 2 and a remainder of 639.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1380 from 2019 leaves us with 639.
Fetch the next digit (0) from the dividend, attach it to 639 and continue: 6390 / 690

On to step 5:
6390 divided by 690 is 9 with a remainder of 180.
Write down 9 as next digit of the result. 
Result so far: 129.0
The remainder is 180 after subtracting 6210 from 6390.
Take the next digit (1) from the dividend and append it to 180, then repeat: 1801 / 690

Going ahead to step 6:
1801 divided by 690 is 2 with a remainder of 421.
Use 2 as the next digit of our solution. 
Result so far: 1292.0
Deduct 1380 from 1801 and we're left with 421.
Fetch the next digit (9) from the dividend, attach it to 421 and continue: 4219 / 690

Step 7:
The number 690 fits into 4219 6 times, leaving a remainder of 79.
The next digit of our result is 6. 
Result so far: 12926.0
Subtracting 4140 from 4219 leaves us with 79.
Fetch the next digit (4) from the dividend, attach it to 79 and continue: 794 / 690

Step 8:
If we divide 794 by 690, we get 1 and a remainder of 104.
The next digit of our result is 1. 
Result so far: 129261.0
The remainder is 104 after subtracting 690 from 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 9:
If we divide 1040 by 690, we get 1 and a remainder of 350.
The number 1 becomes the next digit in our result. 
Result so far: 129261.1
The remainder is 350 after subtracting 690 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 10:
3500 divided by 690 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 129261.15
If we subtract 3450 from 3500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
If we divide 500 by 690, we get 0 and a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 129261.15
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 12:
690 goes into 5000 7 times with a remainder of 170.
Use 7 as the next digit of our solution. 
Result so far: 129261.1507
Subtracting 4830 from 5000 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 13:
If we divide 1700 by 690, we get 2 and a remainder of 320.
The next digit of our result is 2. 
Result so far: 129261.15072
Subtract 1380 from 1700 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
3200 divided by 690 is 4 with a remainder of 440.
The next digit of our result is 4. 
Result so far: 129261.150724
If we take 2760 away from 3200, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 15:
The number 690 fits into 4400 6 times, leaving a remainder of 260.
The next digit of our result is 6. 
Result so far: 129261.1507246
Deduct 4140 from 4400 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 16:
2600 divided by 690 is 3 with a remainder of 530.
The number 3 becomes the next digit in our result. 
Result so far: 129261.15072463
Subtract 2070 from 2600 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

In conclusion, the division gives 129261.15072463 with a balance of 5.3e-07.
