84649780 ÷ 890 
The aim is to understand the frequency of 890 in 84649780.

Going ahead to step 1:
890 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 890

Let's proceed to step 2:
If we divide 84 by 890, we get 0 and a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Grab the next digit (6) from the dividend, add it to 84, then carry on: 846 / 890

Going ahead to step 3:
890 goes into 846 0 times with a remainder of 846.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 846 and we're left with 846.
Take the next digit (4) from the dividend and append it to 846, then repeat: 8464 / 890

On to step 4:
If we divide 8464 by 890, we get 9 and a remainder of 454.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 8010 from 8464 leaves us with 454.
Take the next digit (9) from the dividend and append it to 454, then repeat: 4549 / 890

Going ahead to step 5:
890 can be fit into 4549 5 times, resulting in a remainder of 99.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Deduct 4450 from 4549 and we're left with 99.
Grab the next digit (7) from the dividend, add it to 99, then carry on: 997 / 890

Let's proceed to step 6:
The number 890 fits into 997 1 times, leaving a remainder of 107.
The next digit of our result is 1. 
Result so far: 951.0
Subtracting 890 from 997 leaves us with 107.
Append the next digit (8) from the dividend to 107 and continue with: 1078 / 890

Let's proceed to step 7:
1078 divided by 890 is 1 with a remainder of 188.
Write down 1 as next digit of the result. 
Result so far: 9511.0
If we take 890 away from 1078, we end up with 188.
Append the next digit (0) from the dividend to 188 and continue with: 1880 / 890

Going ahead to step 8:
The number 890 fits into 1880 2 times, leaving a remainder of 100.
Put 2 as the next digit of the answer. 
Result so far: 95112.0
If we subtract 1780 from 1880, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 9:
When dividing 1000 by 890, we get 1 with a remainder of 110.
Record the quotient 1 as the next digit in the result. 
Result so far: 95112.1
Deduct 890 from 1000 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
When dividing 1100 by 890, we get 1 with a remainder of 210.
The number 1 becomes the next digit in our result. 
Result so far: 95112.11
The remainder is 210 after subtracting 890 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final result is 95112.11 with a remainder of 0.21.
