We divide 78086664 by 690
The aim is to understand the frequency of 690 in 78086664.

On to step 1:
690 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 690

Going ahead to step 2:
If we divide 78 by 690, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 690

On to step 3:
When dividing 780 by 690, we get 1 with a remainder of 90.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 690 from 780 and we're left with 90.
Append the next digit (8) from the dividend to 90 and continue with: 908 / 690

Advancing to step 4:
690 goes into 908 1 times with a remainder of 218.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 690 from 908 leaves us with 218.
Take the next digit (6) from the dividend and append it to 218, then repeat: 2186 / 690

Let's proceed to step 5:
2186 divided by 690 is 3 with a remainder of 116.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
Deduct 2070 from 2186 and we're left with 116.
Bring next digit (6) of the dividend behind the 116 and repeat the process: 1166 / 690

Going ahead to step 6:
If we divide 1166 by 690, we get 1 and a remainder of 476.
The next digit of our result is 1. 
Result so far: 1131.0
Subtracting 690 from 1166 leaves us with 476.
Grab the next digit (6) from the dividend, add it to 476, then carry on: 4766 / 690

Going ahead to step 7:
If we divide 4766 by 690, we get 6 and a remainder of 626.
Record the quotient 6 as the next digit in the result. 
Result so far: 11316.0
Subtracting 4140 from 4766 leaves us with 626.
Append the next digit (4) from the dividend to 626 and continue with: 6264 / 690

Moving on to step 8:
If we divide 6264 by 690, we get 9 and a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 113169.0
Deduct 6210 from 6264 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
690 can be fit into 540 0 times, resulting in a remainder of 540.
Put 0 as the next digit of the answer. 
Result so far: 113169.0
If we subtract 0 from 540, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 10:
When dividing 5400 by 690, we get 7 with a remainder of 570.
The next digit of our result is 7. 
Result so far: 113169.07
Subtracting 4830 from 5400 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 11:
The number 690 fits into 5700 8 times, leaving a remainder of 180.
The number 8 becomes the next digit in our result. 
Result so far: 113169.078
The remainder is 180 after subtracting 5520 from 5700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 12:
When dividing 1800 by 690, we get 2 with a remainder of 420.
Use 2 as the next digit of our solution. 
Result so far: 113169.0782
The remainder is 420 after subtracting 1380 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 13:
The number 690 fits into 4200 6 times, leaving a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 113169.07826
Subtract 4140 from 4200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
If we divide 600 by 690, we get 0 and a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 113169.07826
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 15:
6000 divided by 690 is 8 with a remainder of 480.
The number 8 becomes the next digit in our result. 
Result so far: 113169.0782608
Subtracting 5520 from 6000 leaves us 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.

Let's proceed to step 16:
The number 690 fits into 4800 6 times, leaving a remainder of 660.
Record the quotient 6 as the next digit in the result. 
Result so far: 113169.07826086
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.

Our division results in 113169.07826086 with a remaining 6.6e-07.
