We're dividing 351907 by 87 
Our goal is to divide 351907 by 87.

Advancing to step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 87

Going ahead to step 2:
When dividing 35 by 87, we get 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 87

On to step 3:
87 can be fit into 351 4 times, resulting in a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 348 from 351 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 87

Going ahead to step 4:
87 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 39, we end up with 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 87

Let's proceed to step 5:
87 goes into 390 4 times with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 404.0
If we take 348 away from 390, we end up with 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 87

Step 6:
If we divide 427 by 87, we get 4 and a remainder of 79.
The number 4 becomes the next digit in our result. 
Result so far: 4044.0
Subtracting 348 from 427 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 7:
When dividing 790 by 87, we get 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 4044.9
If we take 783 away from 790, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
70 divided by 87 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 4044.9
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
The number 87 fits into 700 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 4044.908
The remainder is 4 after subtracting 696 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
87 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4044.908
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
87 goes into 400 4 times with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 4044.90804
Deduct 348 from 400 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 12:
The number 87 fits into 520 5 times, leaving a remainder of 85.
The next digit of our result is 5. 
Result so far: 4044.908045
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.

On to step 13:
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: 4044.9080459
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.

Step 14:
When dividing 670 by 87, we get 7 with a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 4044.90804597
If we subtract 609 from 670, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 4044.90804597 with a remaining 6.1e-08.
