Let's divide 89711343 by 406
The aim is to understand the frequency of 406 in 89711343.

Going ahead to step 1:
The number 406 fits into 8 0 times, leaving 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.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 406

Advancing to step 2:
If we divide 89 by 406, we get 0 and a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Include the next digit (7) from the dividend after 89, then repeat: 897 / 406

Step 3:
The number 406 fits into 897 2 times, leaving a remainder of 85.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 812 from 897 and we're left with 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 406

On to step 4:
406 goes into 851 2 times with a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 812 away from 851, we end up with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 406

Step 5:
When dividing 391 by 406, we get 0 with a remainder of 391.
Use 0 as the next digit of our solution. 
Result so far: 220.0
Subtract 0 from 391 to get 391.
Append the next digit (3) from the dividend to 391 and continue with: 3913 / 406

Moving on to step 6:
If we divide 3913 by 406, we get 9 and a remainder of 259.
Write down 9 as next digit of the result. 
Result so far: 2209.0
Subtract 3654 from 3913 to get 259.
Grab the next digit (4) from the dividend, add it to 259, then carry on: 2594 / 406

Let's proceed to step 7:
When dividing 2594 by 406, we get 6 with a remainder of 158.
Record the quotient 6 as the next digit in the result. 
Result so far: 22096.0
If we take 2436 away from 2594, we end up with 158.
Fetch the next digit (3) from the dividend, attach it to 158 and continue: 1583 / 406

Step 8:
When dividing 1583 by 406, we get 3 with a remainder of 365.
Use 3 as the next digit of our solution. 
Result so far: 220963.0
The remainder is 365 after subtracting 1218 from 1583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 9:
When dividing 3650 by 406, we get 8 with a remainder of 402.
Record the quotient 8 as the next digit in the result. 
Result so far: 220963.8
Deduct 3248 from 3650 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 10:
406 can be fit into 4020 9 times, resulting in a remainder of 366.
The number 9 becomes the next digit in our result. 
Result so far: 220963.89
If we take 3654 away from 4020, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

On to step 11:
3660 divided by 406 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 220963.899
Subtract 3654 from 3660 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 220963.899, and the remainder is 0.0006.
