We look at the division of 85321428 by 946 
The aim is to understand the frequency of 946 in 85321428.

Step 1:
If we divide 8 by 946, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 946

Step 2:
946 can be fit into 85 0 times, resulting in a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Bring next digit (3) of the dividend behind the 85 and repeat the process: 853 / 946

Moving on to step 3:
946 can be fit into 853 0 times, resulting in a remainder of 853.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 853 and we're left with 853.
Append the next digit (2) from the dividend to 853 and continue with: 8532 / 946

Advancing to step 4:
946 goes into 8532 9 times with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 8514 from 8532, we get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 946

Moving on to step 5:
If we divide 181 by 946, we get 0 and a remainder of 181.
The next digit of our result is 0. 
Result so far: 90.0
Deduct 0 from 181 and we're left with 181.
Grab the next digit (4) from the dividend, add it to 181, then carry on: 1814 / 946

Advancing to step 6:
946 can be fit into 1814 1 times, resulting in a remainder of 868.
Put 1 as the next digit of the answer. 
Result so far: 901.0
Subtract 946 from 1814 to get 868.
Bring next digit (2) of the dividend behind the 868 and repeat the process: 8682 / 946

Advancing to step 7:
8682 divided by 946 is 9 with a remainder of 168.
The number 9 becomes the next digit in our result. 
Result so far: 9019.0
Subtracting 8514 from 8682 leaves us with 168.
Take the next digit (8) from the dividend and append it to 168, then repeat: 1688 / 946

Advancing to step 8:
946 can be fit into 1688 1 times, resulting in a remainder of 742.
Use 1 as the next digit of our solution. 
Result so far: 90191.0
Subtracting 946 from 1688 leaves us with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

On to step 9:
946 goes into 7420 7 times with a remainder of 798.
The next digit of our result is 7. 
Result so far: 90191.7
The remainder is 798 after subtracting 6622 from 7420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Advancing to step 10:
If we divide 7980 by 946, we get 8 and a remainder of 412.
Write down 8 as next digit of the result. 
Result so far: 90191.78
Subtracting 7568 from 7980 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 11:
4120 divided by 946 is 4 with a remainder of 336.
Record the quotient 4 as the next digit in the result. 
Result so far: 90191.784
Deduct 3784 from 4120 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 12:
When dividing 3360 by 946, we get 3 with a remainder of 522.
Use 3 as the next digit of our solution. 
Result so far: 90191.7843
Deduct 2838 from 3360 and we're left with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Let's proceed to step 13:
The number 946 fits into 5220 5 times, leaving a remainder of 490.
Record the quotient 5 as the next digit in the result. 
Result so far: 90191.78435
Subtracting 4730 from 5220 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 14:
4900 divided by 946 is 5 with a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 90191.784355
Subtract 4730 from 4900 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final result is 90191.784355 with a remainder of 1.7e-05.
