402841 divided by 86 
Our goal is to divide 402841 by 86.

Moving on to step 1:
The number 86 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 86

Moving on to step 2:
If we divide 40 by 86, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 86

On to step 3:
86 goes into 402 4 times with a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 344 from 402, we get 58.
Include the next digit (8) from the dividend after 58, then repeat: 588 / 86

Going ahead to step 4:
588 divided by 86 is 6 with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 46.0
Deduct 516 from 588 and we're left with 72.
Take the next digit (4) from the dividend and append it to 72, then repeat: 724 / 86

Going ahead to step 5:
86 goes into 724 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 468.0
If we take 688 away from 724, we end up with 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 86

Advancing to step 6:
When dividing 361 by 86, we get 4 with a remainder of 17.
The next digit of our result is 4. 
Result so far: 4684.0
If we subtract 344 from 361, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
If we divide 170 by 86, we get 1 and a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 4684.1
If we take 86 away from 170, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 8:
The number 86 fits into 840 9 times, leaving a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 4684.19
Deduct 774 from 840 and we're left 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.

Step 9:
The number 86 fits into 660 7 times, leaving a remainder of 58.
The next digit of our result is 7. 
Result so far: 4684.197
Subtract 602 from 660 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
The number 86 fits into 580 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 4684.1976
If we take 516 away from 580, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
640 divided by 86 is 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 4684.19767
Subtract 602 from 640 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
86 goes into 380 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 4684.197674
Deduct 344 from 380 and we're left 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.

Advancing to step 13:
If we divide 360 by 86, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 4684.1976744
Deduct 344 from 360 and we're left 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.
