We look at the division of 77869739 by 890 
The aim is to understand the frequency of 890 in 77869739.

Let's proceed to step 1:
If we divide 7 by 890, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 890

Let's proceed to step 2:
The number 890 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 890

Moving on to step 3:
When dividing 778 by 890, we get 0 with a remainder of 778.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 778 to get 778.
Take the next digit (6) from the dividend and append it to 778, then repeat: 7786 / 890

Advancing to step 4:
890 can be fit into 7786 8 times, resulting in a remainder of 666.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 7120 away from 7786, we end up with 666.
Fetch the next digit (9) from the dividend, attach it to 666 and continue: 6669 / 890

On to step 5:
When dividing 6669 by 890, we get 7 with a remainder of 439.
Write down 7 as next digit of the result. 
Result so far: 87.0
The remainder is 439 after subtracting 6230 from 6669.
Grab the next digit (7) from the dividend, add it to 439, then carry on: 4397 / 890

Moving on to step 6:
890 goes into 4397 4 times with a remainder of 837.
Put 4 as the next digit of the answer. 
Result so far: 874.0
Subtract 3560 from 4397 to get 837.
Take the next digit (3) from the dividend and append it to 837, then repeat: 8373 / 890

Going ahead to step 7:
When dividing 8373 by 890, we get 9 with a remainder of 363.
Record the quotient 9 as the next digit in the result. 
Result so far: 8749.0
The remainder is 363 after subtracting 8010 from 8373.
Fetch the next digit (9) from the dividend, attach it to 363 and continue: 3639 / 890

Step 8:
When dividing 3639 by 890, we get 4 with a remainder of 79.
The number 4 becomes the next digit in our result. 
Result so far: 87494.0
If we subtract 3560 from 3639, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 9:
790 divided by 890 is 0 with a remainder of 790.
Record the quotient 0 as the next digit in the result. 
Result so far: 87494.0
Subtract 0 from 790 to get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Moving on to step 10:
The number 890 fits into 7900 8 times, leaving a remainder of 780.
Put 8 as the next digit of the answer. 
Result so far: 87494.08
If we subtract 7120 from 7900, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Going ahead to step 11:
7800 divided by 890 is 8 with a remainder of 680.
Put 8 as the next digit of the answer. 
Result so far: 87494.088
Deduct 7120 from 7800 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

The final result is 87494.088 with a remainder of 0.068.
