We're dividing 85902074 by 434 
Let's see how many times 434 fits into 85902074.

On to step 1:
434 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 434

On to step 2:
434 can be fit into 85 0 times, resulting in a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Include the next digit (9) from the dividend after 85, then repeat: 859 / 434

On to step 3:
If we divide 859 by 434, we get 1 and a remainder of 425.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 434 from 859 leaves us with 425.
Grab the next digit (0) from the dividend, add it to 425, then carry on: 4250 / 434

Advancing to step 4:
434 goes into 4250 9 times with a remainder of 344.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 3906 away from 4250, we end up with 344.
Bring next digit (2) of the dividend behind the 344 and repeat the process: 3442 / 434

Going ahead to step 5:
434 goes into 3442 7 times with a remainder of 404.
The next digit of our result is 7. 
Result so far: 197.0
If we subtract 3038 from 3442, we get 404.
Bring next digit (0) of the dividend behind the 404 and repeat the process: 4040 / 434

Going ahead to step 6:
The number 434 fits into 4040 9 times, leaving a remainder of 134.
Use 9 as the next digit of our solution. 
Result so far: 1979.0
Subtracting 3906 from 4040 leaves us with 134.
Append the next digit (7) from the dividend to 134 and continue with: 1347 / 434

Going ahead to step 7:
If we divide 1347 by 434, we get 3 and a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 19793.0
If we take 1302 away from 1347, we end up with 45.
Grab the next digit (4) from the dividend, add it to 45, then carry on: 454 / 434

Advancing to step 8:
434 goes into 454 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 197931.0
Subtracting 434 from 454 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.

Step 9:
434 can be fit into 200 0 times, resulting in a remainder of 200.
The next digit of our result is 0. 
Result so far: 197931.0
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
If we divide 2000 by 434, we get 4 and a remainder of 264.
Write down 4 as next digit of the result. 
Result so far: 197931.04
Subtract 1736 from 2000 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 11:
2640 divided by 434 is 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 197931.046
If we take 2604 away from 2640, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
If we divide 360 by 434, we get 0 and a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 197931.046
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 13:
3600 divided by 434 is 8 with a remainder of 128.
Record the quotient 8 as the next digit in the result. 
Result so far: 197931.04608
Subtracting 3472 from 3600 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 14:
When dividing 1280 by 434, we get 2 with a remainder of 412.
Use 2 as the next digit of our solution. 
Result so far: 197931.046082
Subtracting 868 from 1280 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 15:
4120 divided by 434 is 9 with a remainder of 214.
Write down 9 as next digit of the result. 
Result so far: 197931.0460829
If we subtract 3906 from 4120, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 16:
434 goes into 2140 4 times with a remainder of 404.
Put 4 as the next digit of the answer. 
Result so far: 197931.04608294
Deduct 1736 from 2140 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

The final outcome is 197931.04608294, with a leftover of 4.04e-07.
