81466551 divided by 690 
The aim is to understand the frequency of 690 in 81466551.

On to step 1:
If we divide 8 by 690, 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 (1) from the dividend to 8 and continue with: 81 / 690

Advancing to step 2:
690 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (4) of the dividend behind the 81 and repeat the process: 814 / 690

On to step 3:
690 goes into 814 1 times with a remainder of 124.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 690 away from 814, we end up with 124.
Append the next digit (6) from the dividend to 124 and continue with: 1246 / 690

Step 4:
The number 690 fits into 1246 1 times, leaving a remainder of 556.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 690 away from 1246, we end up with 556.
Grab the next digit (6) from the dividend, add it to 556, then carry on: 5566 / 690

On to step 5:
690 can be fit into 5566 8 times, resulting in a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 118.0
Subtract 5520 from 5566 to get 46.
Append the next digit (5) from the dividend to 46 and continue with: 465 / 690

Advancing to step 6:
690 goes into 465 0 times with a remainder of 465.
Put 0 as the next digit of the answer. 
Result so far: 1180.0
The remainder is 465 after subtracting 0 from 465.
Append the next digit (5) from the dividend to 465 and continue with: 4655 / 690

Advancing to step 7:
690 goes into 4655 6 times with a remainder of 515.
Record the quotient 6 as the next digit in the result. 
Result so far: 11806.0
Deduct 4140 from 4655 and we're left with 515.
Grab the next digit (1) from the dividend, add it to 515, then carry on: 5151 / 690

Step 8:
If we divide 5151 by 690, we get 7 and a remainder of 321.
Write down 7 as next digit of the result. 
Result so far: 118067.0
If we take 4830 away from 5151, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 9:
When dividing 3210 by 690, we get 4 with a remainder of 450.
The number 4 becomes the next digit in our result. 
Result so far: 118067.4
If we take 2760 away from 3210, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 10:
When dividing 4500 by 690, we get 6 with a remainder of 360.
Use 6 as the next digit of our solution. 
Result so far: 118067.46
Subtracting 4140 from 4500 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 11:
If we divide 3600 by 690, we get 5 and a remainder of 150.
The next digit of our result is 5. 
Result so far: 118067.465
Subtract 3450 from 3600 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
When dividing 1500 by 690, we get 2 with a remainder of 120.
Write down 2 as next digit of the result. 
Result so far: 118067.4652
Subtract 1380 from 1500 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 13:
1200 divided by 690 is 1 with a remainder of 510.
The number 1 becomes the next digit in our result. 
Result so far: 118067.46521
The remainder is 510 after subtracting 690 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 14:
When dividing 5100 by 690, we get 7 with a remainder of 270.
The number 7 becomes the next digit in our result. 
Result so far: 118067.465217
The remainder is 270 after subtracting 4830 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 15:
690 goes into 2700 3 times with a remainder of 630.
Use 3 as the next digit of our solution. 
Result so far: 118067.4652173
Subtracting 2070 from 2700 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 16:
690 can be fit into 6300 9 times, resulting in a remainder of 90.
The next digit of our result is 9. 
Result so far: 118067.46521739
The remainder is 90 after subtracting 6210 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final result is 118067.46521739 with a remainder of 9e-08.
