We look at the division of 169198 by 3 
We want to divide 169198 by 3.

On to step 1:
If we divide 1 by 3, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 3

Going ahead to step 2:
If we divide 16 by 3, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 1 after subtracting 15 from 16.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 3

On to step 3:
3 goes into 19 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we subtract 18 from 19, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 3

Let's proceed to step 4:
11 divided by 3 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 563.0
Deduct 9 from 11 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Let's proceed to step 5:
If we divide 29 by 3, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 5639.0
Deduct 27 from 29 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 3

Advancing to step 6:
28 divided by 3 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 56399.0
Deduct 27 from 28 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 56399.3
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
3 goes into 10 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 56399.33
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 56399.33 with a remaining 0.001.
