985429 divided by 86 
We want to divide 985429 by 86.

Moving on to step 1:
The number 86 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 86

Step 2:
When dividing 98 by 86, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 86 from 98 and we're left with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 86

Going ahead to step 3:
If we divide 125 by 86, we get 1 and a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 86 away from 125, we end up with 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 86

Step 4:
86 goes into 394 4 times with a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Subtracting 344 from 394 leaves us with 50.
Grab the next digit (2) from the dividend, add it to 50, then carry on: 502 / 86

Going ahead to step 5:
The number 86 fits into 502 5 times, leaving a remainder of 72.
The next digit of our result is 5. 
Result so far: 1145.0
Subtract 430 from 502 to get 72.
Grab the next digit (9) from the dividend, add it to 72, then carry on: 729 / 86

Step 6:
729 divided by 86 is 8 with a remainder of 41.
The next digit of our result is 8. 
Result so far: 11458.0
If we take 688 away from 729, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
When dividing 410 by 86, we get 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 11458.4
If we take 344 away from 410, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 8:
The number 86 fits into 660 7 times, leaving a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 11458.47
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
The number 86 fits into 580 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 11458.476
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
The number 86 fits into 640 7 times, leaving a remainder of 38.
The next digit of our result is 7. 
Result so far: 11458.4767
If we take 602 away from 640, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
When dividing 380 by 86, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 11458.47674
If we take 344 away from 380, 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.

Step 12:
86 goes into 360 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 11458.476744
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 11458.476744 and a remainder of 1.6e-06.
