We're dividing 342929 by 87 
We want to figure out the number of times 342929 can be divided by 87.

Advancing to step 1:
The number 87 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 87

Moving on to step 2:
If we divide 34 by 87, we get 0 and a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 87

Going ahead to step 3:
When dividing 342 by 87, we get 3 with a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 261 from 342, we get 81.
Fetch the next digit (9) from the dividend, attach it to 81 and continue: 819 / 87

Moving on to step 4:
The number 87 fits into 819 9 times, leaving a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we subtract 783 from 819, we get 36.
Fetch the next digit (2) from the dividend, attach it to 36 and continue: 362 / 87

Step 5:
87 goes into 362 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 394.0
Subtracting 348 from 362 leaves us with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 87

Step 6:
The number 87 fits into 149 1 times, leaving a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 3941.0
Subtract 87 from 149 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 7:
When dividing 620 by 87, we get 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 3941.7
The remainder is 11 after subtracting 609 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
87 goes into 110 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 3941.71
If we take 87 away from 110, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
When dividing 230 by 87, we get 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 3941.712
Subtract 174 from 230 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
If we divide 560 by 87, we get 6 and a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 3941.7126
Subtract 522 from 560 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.

Step 11:
When dividing 380 by 87, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 3941.71264
Deduct 348 from 380 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
If we divide 320 by 87, we get 3 and a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 3941.712643
Deduct 261 from 320 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 13:
The number 87 fits into 590 6 times, leaving a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 3941.7126436
Deduct 522 from 590 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 14:
The number 87 fits into 680 7 times, leaving a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 3941.71264367
If we take 609 away from 680, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final outcome is 3941.71264367, with a leftover of 7.1e-08.
