We're dividing 351346 by 87 
We want to figure out the number of times 351346 can be divided by 87.

Step 1:
When dividing 3 by 87, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 87

Advancing to step 2:
The number 87 fits into 35 0 times, leaving a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 87

Going ahead to step 3:
If we divide 351 by 87, we get 4 and a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 348 from 351 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 87

Moving on to step 4:
87 can be fit into 33 0 times, resulting in a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtract 0 from 33 to get 33.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 87

Let's proceed to step 5:
If we divide 334 by 87, we get 3 and a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 403.0
If we subtract 261 from 334, we get 73.
Grab the next digit (6) from the dividend, add it to 73, then carry on: 736 / 87

Going ahead to step 6:
87 goes into 736 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 4038.0
The remainder is 40 after subtracting 696 from 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
400 divided by 87 is 4 with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 4038.4
Subtract 348 from 400 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.

On to step 8:
87 can be fit into 520 5 times, resulting in a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 4038.45
Subtracting 435 from 520 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 9:
The number 87 fits into 850 9 times, leaving a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 4038.459
Subtract 783 from 850 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 10:
The number 87 fits into 670 7 times, leaving a remainder of 61.
The next digit of our result is 7. 
Result so far: 4038.4597
If we take 609 away from 670, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 11:
If we divide 610 by 87, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 4038.45977
Subtracting 609 from 610 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 4038.45977 and a remainder of 1e-06.
