We look at the division of 85266921 by 506 
We want to divide 85266921 by 506.

Moving on to step 1:
When dividing 8 by 506, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 506

Moving on to step 2:
506 can be fit into 85 0 times, resulting in a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Take the next digit (2) from the dividend and append it to 85, then repeat: 852 / 506

Going ahead to step 3:
506 goes into 852 1 times with a remainder of 346.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 346 after subtracting 506 from 852.
Include the next digit (6) from the dividend after 346, then repeat: 3466 / 506

Advancing to step 4:
When dividing 3466 by 506, we get 6 with a remainder of 430.
The next digit of our result is 6. 
Result so far: 16.0
If we take 3036 away from 3466, we end up with 430.
Fetch the next digit (6) from the dividend, attach it to 430 and continue: 4306 / 506

Let's proceed to step 5:
The number 506 fits into 4306 8 times, leaving a remainder of 258.
Use 8 as the next digit of our solution. 
Result so far: 168.0
Deduct 4048 from 4306 and we're left with 258.
Fetch the next digit (9) from the dividend, attach it to 258 and continue: 2589 / 506

Let's proceed to step 6:
The number 506 fits into 2589 5 times, leaving a remainder of 59.
Record the quotient 5 as the next digit in the result. 
Result so far: 1685.0
Subtract 2530 from 2589 to get 59.
Take the next digit (2) from the dividend and append it to 59, then repeat: 592 / 506

Advancing to step 7:
If we divide 592 by 506, we get 1 and a remainder of 86.
The next digit of our result is 1. 
Result so far: 16851.0
If we take 506 away from 592, we end up with 86.
Fetch the next digit (1) from the dividend, attach it to 86 and continue: 861 / 506

Moving on to step 8:
When dividing 861 by 506, we get 1 with a remainder of 355.
Put 1 as the next digit of the answer. 
Result so far: 168511.0
If we take 506 away from 861, we end up with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 9:
The number 506 fits into 3550 7 times, leaving a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 168511.7
Subtract 3542 from 3550 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.

On to step 10:
When dividing 80 by 506, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 168511.7
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
506 goes into 800 1 times with a remainder of 294.
Put 1 as the next digit of the answer. 
Result so far: 168511.701
The remainder is 294 after subtracting 506 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 12:
506 goes into 2940 5 times with a remainder of 410.
Write down 5 as next digit of the result. 
Result so far: 168511.7015
The remainder is 410 after subtracting 2530 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 13:
The number 506 fits into 4100 8 times, leaving a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 168511.70158
Subtract 4048 from 4100 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 14:
506 can be fit into 520 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 168511.701581
Subtracting 506 from 520 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 15:
140 divided by 506 is 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 168511.701581
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 16:
1400 divided by 506 is 2 with a remainder of 388.
Use 2 as the next digit of our solution. 
Result so far: 168511.70158102
Subtract 1012 from 1400 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

The final result is 168511.70158102 with a remainder of 3.88e-07.
