We look at the division of 373353 by 87 
We want to figure out the number of times 373353 can be divided by 87.

Going ahead to step 1:
The number 87 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 87

Going ahead to step 2:
37 divided by 87 is 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 87

Going ahead to step 3:
87 goes into 373 4 times with a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 348 from 373 and we're left with 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 87

Going ahead to step 4:
253 divided by 87 is 2 with a remainder of 79.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 174 from 253 to get 79.
Bring next digit (5) of the dividend behind the 79 and repeat the process: 795 / 87

Going ahead to step 5:
795 divided by 87 is 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 429.0
If we take 783 away from 795, we end up with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 87

Advancing to step 6:
87 goes into 123 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 4291.0
Subtracting 87 from 123 leaves us 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 7:
87 goes into 360 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 4291.4
If we take 348 away from 360, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
120 divided by 87 is 1 with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 4291.41
Subtracting 87 from 120 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
When dividing 330 by 87, we get 3 with a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 4291.413
If we take 261 away from 330, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 10:
87 can be fit into 690 7 times, resulting in a remainder of 81.
Write down 7 as next digit of the result. 
Result so far: 4291.4137
The remainder is 81 after subtracting 609 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 11:
When dividing 810 by 87, we get 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 4291.41379
The remainder is 27 after subtracting 783 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
When dividing 270 by 87, we get 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 4291.413793
Subtracting 261 from 270 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 13:
The number 87 fits into 90 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 4291.4137931
Deduct 87 from 90 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
If we divide 30 by 87, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 4291.4137931
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 4291.4137931, with a leftover of 3e-08.
