We look at the division of 628405 by 87 
We're looking to find how many times 87 goes into 628405.

Let's proceed to step 1:
87 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 87

Advancing to step 2:
If we divide 62 by 87, we get 0 and a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Bring next digit (8) of the dividend behind the 62 and repeat the process: 628 / 87

Moving on to step 3:
87 goes into 628 7 times with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 609 from 628 and we're left with 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 87

On to step 4:
If we divide 194 by 87, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Subtracting 174 from 194 leaves us with 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 87

Let's proceed to step 5:
When dividing 200 by 87, we get 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 722.0
If we take 174 away from 200, we end up with 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 87

On to step 6:
265 divided by 87 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 7223.0
Subtract 261 from 265 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
If we divide 40 by 87, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7223.0
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.

Going ahead to step 8:
400 divided by 87 is 4 with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 7223.04
If we subtract 348 from 400, we 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.

Moving on to step 9:
The number 87 fits into 520 5 times, leaving a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 7223.045
Subtract 435 from 520 to get 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 10:
When dividing 850 by 87, we get 9 with a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 7223.0459
Subtracting 783 from 850 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 11:
87 can be fit into 670 7 times, resulting in a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 7223.04597
The remainder is 61 after subtracting 609 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
87 can be fit into 610 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 7223.045977
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.

The final outcome is 7223.045977, with a leftover of 1e-07.
