We're dividing 75385156 by 849 
The aim is to understand the frequency of 849 in 75385156.

On to step 1:
The number 849 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 849

Step 2:
849 can be fit into 75 0 times, resulting in a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Fetch the next digit (3) from the dividend, attach it to 75 and continue: 753 / 849

Step 3:
The number 849 fits into 753 0 times, leaving a remainder of 753.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 753, we get 753.
Grab the next digit (8) from the dividend, add it to 753, then carry on: 7538 / 849

Moving on to step 4:
849 goes into 7538 8 times with a remainder of 746.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 6792 from 7538 and we're left with 746.
Fetch the next digit (5) from the dividend, attach it to 746 and continue: 7465 / 849

Advancing to step 5:
The number 849 fits into 7465 8 times, leaving a remainder of 673.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtracting 6792 from 7465 leaves us with 673.
Bring next digit (1) of the dividend behind the 673 and repeat the process: 6731 / 849

Moving on to step 6:
849 can be fit into 6731 7 times, resulting in a remainder of 788.
Put 7 as the next digit of the answer. 
Result so far: 887.0
Deduct 5943 from 6731 and we're left with 788.
Include the next digit (5) from the dividend after 788, then repeat: 7885 / 849

On to step 7:
When dividing 7885 by 849, we get 9 with a remainder of 244.
Write down 9 as next digit of the result. 
Result so far: 8879.0
The remainder is 244 after subtracting 7641 from 7885.
Take the next digit (6) from the dividend and append it to 244, then repeat: 2446 / 849

On to step 8:
If we divide 2446 by 849, we get 2 and a remainder of 748.
Write down 2 as next digit of the result. 
Result so far: 88792.0
If we take 1698 away from 2446, we end up with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Advancing to step 9:
If we divide 7480 by 849, we get 8 and a remainder of 688.
Use 8 as the next digit of our solution. 
Result so far: 88792.8
If we take 6792 away from 7480, we end up with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

On to step 10:
When dividing 6880 by 849, we get 8 with a remainder of 88.
The next digit of our result is 8. 
Result so far: 88792.88
If we subtract 6792 from 6880, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Our division results in 88792.88 with a remaining 0.088.
