88934781 ÷ 690 
The aim is to understand the frequency of 690 in 88934781.

Let's proceed to step 1:
The number 690 fits into 8 0 times, leaving 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.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 690

Step 2:
690 goes into 88 0 times with a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 88, we end up with 88.
Take the next digit (9) from the dividend and append it to 88, then repeat: 889 / 690

Moving on to step 3:
690 can be fit into 889 1 times, resulting in a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 690 from 889 and we're left with 199.
Append the next digit (3) from the dividend to 199 and continue with: 1993 / 690

Step 4:
690 goes into 1993 2 times with a remainder of 613.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 1380 from 1993 to get 613.
Fetch the next digit (4) from the dividend, attach it to 613 and continue: 6134 / 690

Going ahead to step 5:
If we divide 6134 by 690, we get 8 and a remainder of 614.
Use 8 as the next digit of our solution. 
Result so far: 128.0
The remainder is 614 after subtracting 5520 from 6134.
Grab the next digit (7) from the dividend, add it to 614, then carry on: 6147 / 690

On to step 6:
If we divide 6147 by 690, we get 8 and a remainder of 627.
Put 8 as the next digit of the answer. 
Result so far: 1288.0
Deduct 5520 from 6147 and we're left with 627.
Append the next digit (8) from the dividend to 627 and continue with: 6278 / 690

Moving on to step 7:
When dividing 6278 by 690, we get 9 with a remainder of 68.
Record the quotient 9 as the next digit in the result. 
Result so far: 12889.0
The remainder is 68 after subtracting 6210 from 6278.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 690

Moving on to step 8:
690 can be fit into 681 0 times, resulting in a remainder of 681.
The next digit of our result is 0. 
Result so far: 128890.0
Subtract 0 from 681 to get 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Let's proceed to step 9:
690 goes into 6810 9 times with a remainder of 600.
Record the quotient 9 as the next digit in the result. 
Result so far: 128890.9
Subtract 6210 from 6810 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 10:
690 can be fit into 6000 8 times, resulting in a remainder of 480.
Use 8 as the next digit of our solution. 
Result so far: 128890.98
Deduct 5520 from 6000 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 11:
690 can be fit into 4800 6 times, resulting in a remainder of 660.
The number 6 becomes the next digit in our result. 
Result so far: 128890.986
The remainder is 660 after subtracting 4140 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 12:
690 goes into 6600 9 times with a remainder of 390.
The number 9 becomes the next digit in our result. 
Result so far: 128890.9869
The remainder is 390 after subtracting 6210 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 13:
690 can be fit into 3900 5 times, resulting in a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 128890.98695
If we take 3450 away from 3900, 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.

Going ahead to step 14:
If we divide 4500 by 690, we get 6 and a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 128890.986956
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.

Advancing to step 15:
690 can be fit into 3600 5 times, resulting in a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 128890.9869565
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.

Step 16:
If we divide 1500 by 690, we get 2 and a remainder of 120.
Write down 2 as next digit of the result. 
Result so far: 128890.98695652
Deduct 1380 from 1500 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 128890.98695652 with a remaining 1.2e-07.
