We're dividing 85139173 by 559 
We want to figure out the number of times 85139173 can be divided by 559.

Advancing to step 1:
When dividing 8 by 559, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 559

Step 2:
559 goes into 85 0 times with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Fetch the next digit (1) from the dividend, attach it to 85 and continue: 851 / 559

Let's proceed to step 3:
851 divided by 559 is 1 with a remainder of 292.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 292 after subtracting 559 from 851.
Fetch the next digit (3) from the dividend, attach it to 292 and continue: 2923 / 559

Advancing to step 4:
The number 559 fits into 2923 5 times, leaving a remainder of 128.
The next digit of our result is 5. 
Result so far: 15.0
If we take 2795 away from 2923, we end up with 128.
Fetch the next digit (9) from the dividend, attach it to 128 and continue: 1289 / 559

On to step 5:
The number 559 fits into 1289 2 times, leaving a remainder of 171.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
If we subtract 1118 from 1289, we get 171.
Fetch the next digit (1) from the dividend, attach it to 171 and continue: 1711 / 559

Going ahead to step 6:
If we divide 1711 by 559, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 1523.0
If we take 1677 away from 1711, we end up with 34.
Grab the next digit (7) from the dividend, add it to 34, then carry on: 347 / 559

On to step 7:
559 can be fit into 347 0 times, resulting in a remainder of 347.
Use 0 as the next digit of our solution. 
Result so far: 15230.0
The remainder is 347 after subtracting 0 from 347.
Take the next digit (3) from the dividend and append it to 347, then repeat: 3473 / 559

On to step 8:
559 goes into 3473 6 times with a remainder of 119.
Record the quotient 6 as the next digit in the result. 
Result so far: 152306.0
Subtract 3354 from 3473 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 9:
When dividing 1190 by 559, we get 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 152306.2
If we take 1118 away from 1190, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
559 goes into 720 1 times with a remainder of 161.
The next digit of our result is 1. 
Result so far: 152306.21
Deduct 559 from 720 and we're left with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Step 11:
The number 559 fits into 1610 2 times, leaving a remainder of 492.
Put 2 as the next digit of the answer. 
Result so far: 152306.212
If we subtract 1118 from 1610, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Advancing to step 12:
559 goes into 4920 8 times with a remainder of 448.
Use 8 as the next digit of our solution. 
Result so far: 152306.2128
Deduct 4472 from 4920 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 13:
When dividing 4480 by 559, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 152306.21288
Subtract 4472 from 4480 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 152306.21288, with a leftover of 8e-06.
