Let's divide 86751448 by 690
The aim is to understand the frequency of 690 in 86751448.

Let's proceed to step 1:
8 divided by 690 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 690

Moving on to step 2:
86 divided by 690 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (7) from the dividend to 86 and continue with: 867 / 690

Advancing to step 3:
867 divided by 690 is 1 with a remainder of 177.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 690 away from 867, we end up with 177.
Take the next digit (5) from the dividend and append it to 177, then repeat: 1775 / 690

Moving on to step 4:
The number 690 fits into 1775 2 times, leaving a remainder of 395.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1380 from 1775 and we're left with 395.
Grab the next digit (1) from the dividend, add it to 395, then carry on: 3951 / 690

Going ahead to step 5:
When dividing 3951 by 690, we get 5 with a remainder of 501.
Use 5 as the next digit of our solution. 
Result so far: 125.0
If we take 3450 away from 3951, we end up with 501.
Grab the next digit (4) from the dividend, add it to 501, then carry on: 5014 / 690

Step 6:
5014 divided by 690 is 7 with a remainder of 184.
The number 7 becomes the next digit in our result. 
Result so far: 1257.0
Subtracting 4830 from 5014 leaves us with 184.
Bring next digit (4) of the dividend behind the 184 and repeat the process: 1844 / 690

Advancing to step 7:
690 can be fit into 1844 2 times, resulting in a remainder of 464.
Use 2 as the next digit of our solution. 
Result so far: 12572.0
If we subtract 1380 from 1844, we get 464.
Include the next digit (8) from the dividend after 464, then repeat: 4648 / 690

Step 8:
When dividing 4648 by 690, we get 6 with a remainder of 508.
Use 6 as the next digit of our solution. 
Result so far: 125726.0
The remainder is 508 after subtracting 4140 from 4648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Moving on to step 9:
The number 690 fits into 5080 7 times, leaving a remainder of 250.
Record the quotient 7 as the next digit in the result. 
Result so far: 125726.7
If we subtract 4830 from 5080, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 10:
When dividing 2500 by 690, we get 3 with a remainder of 430.
Use 3 as the next digit of our solution. 
Result so far: 125726.73
Subtracting 2070 from 2500 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 11:
If we divide 4300 by 690, we get 6 and a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 125726.736
Deduct 4140 from 4300 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 12:
When dividing 1600 by 690, we get 2 with a remainder of 220.
Record the quotient 2 as the next digit in the result. 
Result so far: 125726.7362
If we subtract 1380 from 1600, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 13:
2200 divided by 690 is 3 with a remainder of 130.
Use 3 as the next digit of our solution. 
Result so far: 125726.73623
Subtracting 2070 from 2200 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 14:
When dividing 1300 by 690, we get 1 with a remainder of 610.
Put 1 as the next digit of the answer. 
Result so far: 125726.736231
Subtract 690 from 1300 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 15:
690 goes into 6100 8 times with a remainder of 580.
Record the quotient 8 as the next digit in the result. 
Result so far: 125726.7362318
If we subtract 5520 from 6100, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 16:
When dividing 5800 by 690, we get 8 with a remainder of 280.
Write down 8 as next digit of the result. 
Result so far: 125726.73623188
If we subtract 5520 from 5800, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 125726.73623188, with a leftover of 2.8e-07.
