85371475 ÷ 990 
The aim is to understand the frequency of 990 in 85371475.

Advancing to step 1:
When dividing 8 by 990, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 990

On to step 2:
When dividing 85 by 990, we get 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Append the next digit (3) from the dividend to 85 and continue with: 853 / 990

Let's proceed to step 3:
The number 990 fits into 853 0 times, leaving a remainder of 853.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 853 to get 853.
Fetch the next digit (7) from the dividend, attach it to 853 and continue: 8537 / 990

Advancing to step 4:
If we divide 8537 by 990, we get 8 and a remainder of 617.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 7920 away from 8537, we end up with 617.
Take the next digit (1) from the dividend and append it to 617, then repeat: 6171 / 990

Let's proceed to step 5:
If we divide 6171 by 990, we get 6 and a remainder of 231.
Use 6 as the next digit of our solution. 
Result so far: 86.0
The remainder is 231 after subtracting 5940 from 6171.
Fetch the next digit (4) from the dividend, attach it to 231 and continue: 2314 / 990

Step 6:
When dividing 2314 by 990, we get 2 with a remainder of 334.
The number 2 becomes the next digit in our result. 
Result so far: 862.0
Deduct 1980 from 2314 and we're left with 334.
Take the next digit (7) from the dividend and append it to 334, then repeat: 3347 / 990

Going ahead to step 7:
990 goes into 3347 3 times with a remainder of 377.
Write down 3 as next digit of the result. 
Result so far: 8623.0
If we take 2970 away from 3347, we end up with 377.
Fetch the next digit (5) from the dividend, attach it to 377 and continue: 3775 / 990

Going ahead to step 8:
990 goes into 3775 3 times with a remainder of 805.
The next digit of our result is 3. 
Result so far: 86233.0
If we take 2970 away from 3775, we end up with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Advancing to step 9:
990 goes into 8050 8 times with a remainder of 130.
Write down 8 as next digit of the result. 
Result so far: 86233.8
Deduct 7920 from 8050 and we're left 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.

Let's proceed to step 10:
When dividing 1300 by 990, we get 1 with a remainder of 310.
Write down 1 as next digit of the result. 
Result so far: 86233.81
Subtract 990 from 1300 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 11:
If we divide 3100 by 990, we get 3 and a remainder of 130.
The next digit of our result is 3. 
Result so far: 86233.813
The remainder is 130 after subtracting 2970 from 3100.
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 12:
1300 divided by 990 is 1 with a remainder of 310.
The number 1 becomes the next digit in our result. 
Result so far: 86233.8131
If we take 990 away from 1300, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 13:
When dividing 3100 by 990, we get 3 with a remainder of 130.
Put 3 as the next digit of the answer. 
Result so far: 86233.81313
Subtracting 2970 from 3100 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.

Let's proceed to step 14:
If we divide 1300 by 990, we get 1 and a remainder of 310.
Write down 1 as next digit of the result. 
Result so far: 86233.813131
If we take 990 away from 1300, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 15:
When dividing 3100 by 990, we get 3 with a remainder of 130.
Put 3 as the next digit of the answer. 
Result so far: 86233.8131313
If we subtract 2970 from 3100, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 16:
When dividing 1300 by 990, we get 1 with a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 86233.81313131
Subtracting 990 from 1300 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Our division results in 86233.81313131 with a remaining 3.1e-07.
