3153555 ÷ 199 
The aim is to understand the frequency of 199 in 3153555.

On to step 1:
3 divided by 199 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 199

Moving on to step 2:
31 divided by 199 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 199

Going ahead to step 3:
199 can be fit into 315 1 times, resulting in a remainder of 116.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 116 after subtracting 199 from 315.
Grab the next digit (3) from the dividend, add it to 116, then carry on: 1163 / 199

Going ahead to step 4:
The number 199 fits into 1163 5 times, leaving a remainder of 168.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 995 from 1163, we get 168.
Fetch the next digit (5) from the dividend, attach it to 168 and continue: 1685 / 199

Going ahead to step 5:
The number 199 fits into 1685 8 times, leaving a remainder of 93.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
Subtract 1592 from 1685 to get 93.
Bring next digit (5) of the dividend behind the 93 and repeat the process: 935 / 199

On to step 6:
199 goes into 935 4 times with a remainder of 139.
Write down 4 as next digit of the result. 
Result so far: 1584.0
If we take 796 away from 935, we end up with 139.
Grab the next digit (5) from the dividend, add it to 139, then carry on: 1395 / 199

On to step 7:
When dividing 1395 by 199, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 15847.0
Subtract 1393 from 1395 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
199 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 15847.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
199 goes into 200 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 15847.01
Subtract 199 from 200 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
The number 199 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 15847.01
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
100 divided by 199 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 15847.01
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 15847.01 and a remainder of 0.001.
