77941652 divided by 890 
The aim is to understand the frequency of 890 in 77941652.

Step 1:
If we divide 7 by 890, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 890

Moving on to step 2:
If we divide 77 by 890, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (9) from the dividend and append it to 77, then repeat: 779 / 890

On to step 3:
If we divide 779 by 890, we get 0 and a remainder of 779.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 779 to get 779.
Grab the next digit (4) from the dividend, add it to 779, then carry on: 7794 / 890

Advancing to step 4:
The number 890 fits into 7794 8 times, leaving a remainder of 674.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 7120 from 7794 leaves us with 674.
Include the next digit (1) from the dividend after 674, then repeat: 6741 / 890

Step 5:
890 goes into 6741 7 times with a remainder of 511.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtracting 6230 from 6741 leaves us with 511.
Grab the next digit (6) from the dividend, add it to 511, then carry on: 5116 / 890

Going ahead to step 6:
If we divide 5116 by 890, we get 5 and a remainder of 666.
Write down 5 as next digit of the result. 
Result so far: 875.0
Deduct 4450 from 5116 and we're left with 666.
Fetch the next digit (5) from the dividend, attach it to 666 and continue: 6665 / 890

Step 7:
890 can be fit into 6665 7 times, resulting in a remainder of 435.
Record the quotient 7 as the next digit in the result. 
Result so far: 8757.0
If we take 6230 away from 6665, we end up with 435.
Include the next digit (2) from the dividend after 435, then repeat: 4352 / 890

On to step 8:
4352 divided by 890 is 4 with a remainder of 792.
The number 4 becomes the next digit in our result. 
Result so far: 87574.0
Subtracting 3560 from 4352 leaves us with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Advancing to step 9:
If we divide 7920 by 890, we get 8 and a remainder of 800.
The next digit of our result is 8. 
Result so far: 87574.8
Deduct 7120 from 7920 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Let's proceed to step 10:
890 can be fit into 8000 8 times, resulting in a remainder of 880.
Write down 8 as next digit of the result. 
Result so far: 87574.88
If we subtract 7120 from 8000, we get 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

The quotient of the division is 87574.88, and the remainder is 0.88.
