We look at the division of 90250668 by 756 
The aim is to understand the frequency of 756 in 90250668.

Let's proceed to step 1:
If we divide 9 by 756, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 756

Step 2:
756 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Append the next digit (2) from the dividend to 90 and continue with: 902 / 756

Let's proceed to step 3:
When dividing 902 by 756, we get 1 with a remainder of 146.
The next digit of our result is 1. 
Result so far: 1.0
If we take 756 away from 902, we end up with 146.
Bring next digit (5) of the dividend behind the 146 and repeat the process: 1465 / 756

Let's proceed to step 4:
756 goes into 1465 1 times with a remainder of 709.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 756 from 1465 and we're left with 709.
Bring next digit (0) of the dividend behind the 709 and repeat the process: 7090 / 756

Advancing to step 5:
If we divide 7090 by 756, we get 9 and a remainder of 286.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Subtract 6804 from 7090 to get 286.
Take the next digit (6) from the dividend and append it to 286, then repeat: 2866 / 756

Moving on to step 6:
2866 divided by 756 is 3 with a remainder of 598.
Use 3 as the next digit of our solution. 
Result so far: 1193.0
Subtracting 2268 from 2866 leaves us with 598.
Append the next digit (6) from the dividend to 598 and continue with: 5986 / 756

Going ahead to step 7:
5986 divided by 756 is 7 with a remainder of 694.
Record the quotient 7 as the next digit in the result. 
Result so far: 11937.0
Subtract 5292 from 5986 to get 694.
Take the next digit (8) from the dividend and append it to 694, then repeat: 6948 / 756

Moving on to step 8:
756 can be fit into 6948 9 times, resulting in a remainder of 144.
Write down 9 as next digit of the result. 
Result so far: 119379.0
Subtracting 6804 from 6948 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 9:
1440 divided by 756 is 1 with a remainder of 684.
Record the quotient 1 as the next digit in the result. 
Result so far: 119379.1
Subtract 756 from 1440 to get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Advancing to step 10:
The number 756 fits into 6840 9 times, leaving a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 119379.19
The remainder is 36 after subtracting 6804 from 6840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
The number 756 fits into 360 0 times, leaving a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 119379.19
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 12:
When dividing 3600 by 756, we get 4 with a remainder of 576.
The next digit of our result is 4. 
Result so far: 119379.1904
Deduct 3024 from 3600 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

On to step 13:
The number 756 fits into 5760 7 times, leaving a remainder of 468.
The number 7 becomes the next digit in our result. 
Result so far: 119379.19047
Subtract 5292 from 5760 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 14:
When dividing 4680 by 756, we get 6 with a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 119379.190476
The remainder is 144 after subtracting 4536 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 15:
The number 756 fits into 1440 1 times, leaving a remainder of 684.
Put 1 as the next digit of the answer. 
Result so far: 119379.1904761
If we subtract 756 from 1440, we get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Moving on to step 16:
When dividing 6840 by 756, we get 9 with a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 119379.19047619
Subtracting 6804 from 6840 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 119379.19047619, with a leftover of 3.6e-08.
