We look at the division of 33160591 by 946 
The aim is to understand the frequency of 946 in 33160591.

Going ahead to step 1:
946 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 946

Going ahead to step 2:
946 can be fit into 33 0 times, resulting in a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 946

Moving on to step 3:
The number 946 fits into 331 0 times, leaving a remainder of 331.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 331, we get 331.
Bring next digit (6) of the dividend behind the 331 and repeat the process: 3316 / 946

Advancing to step 4:
3316 divided by 946 is 3 with a remainder of 478.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 2838 from 3316, we get 478.
Append the next digit (0) from the dividend to 478 and continue with: 4780 / 946

Advancing to step 5:
946 can be fit into 4780 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 35.0
If we subtract 4730 from 4780, we get 50.
Take the next digit (5) from the dividend and append it to 50, then repeat: 505 / 946

Going ahead to step 6:
The number 946 fits into 505 0 times, leaving a remainder of 505.
Record the quotient 0 as the next digit in the result. 
Result so far: 350.0
Deduct 0 from 505 and we're left with 505.
Fetch the next digit (9) from the dividend, attach it to 505 and continue: 5059 / 946

Advancing to step 7:
946 can be fit into 5059 5 times, resulting in a remainder of 329.
Put 5 as the next digit of the answer. 
Result so far: 3505.0
Deduct 4730 from 5059 and we're left with 329.
Append the next digit (1) from the dividend to 329 and continue with: 3291 / 946

On to step 8:
If we divide 3291 by 946, we get 3 and a remainder of 453.
Record the quotient 3 as the next digit in the result. 
Result so far: 35053.0
Subtract 2838 from 3291 to get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Moving on to step 9:
The number 946 fits into 4530 4 times, leaving a remainder of 746.
Record the quotient 4 as the next digit in the result. 
Result so far: 35053.4
Subtracting 3784 from 4530 leaves us with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Going ahead to step 10:
7460 divided by 946 is 7 with a remainder of 838.
Record the quotient 7 as the next digit in the result. 
Result so far: 35053.47
Deduct 6622 from 7460 and we're left with 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

Step 11:
The number 946 fits into 8380 8 times, leaving a remainder of 812.
Use 8 as the next digit of our solution. 
Result so far: 35053.478
If we subtract 7568 from 8380, we get 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Step 12:
946 can be fit into 8120 8 times, resulting in a remainder of 552.
Record the quotient 8 as the next digit in the result. 
Result so far: 35053.4788
Subtract 7568 from 8120 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

The quotient of the division is 35053.4788, and the remainder is 0.00552.
