We're dividing 998143 by 59 
We want to divide 998143 by 59.

Advancing to step 1:
59 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 59

Let's proceed to step 2:
The number 59 fits into 99 1 times, leaving a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 59 away from 99, we end up with 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 59

Going ahead to step 3:
408 divided by 59 is 6 with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 354 from 408, we get 54.
Fetch the next digit (1) from the dividend, attach it to 54 and continue: 541 / 59

On to step 4:
541 divided by 59 is 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
Subtract 531 from 541 to get 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 59

Advancing to step 5:
104 divided by 59 is 1 with a remainder of 45.
The next digit of our result is 1. 
Result so far: 1691.0
Subtracting 59 from 104 leaves us with 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 59

Step 6:
59 goes into 453 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 16917.0
Deduct 413 from 453 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
59 goes into 400 6 times with a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 16917.6
If we subtract 354 from 400, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
59 can be fit into 460 7 times, resulting in a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 16917.67
If we take 413 away from 460, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
59 can be fit into 470 7 times, resulting in a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 16917.677
Deduct 413 from 470 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final outcome is 16917.677, with a leftover of 0.0057.
