We look at the division of 745434 by 87 
Let's see how many times 87 fits into 745434.

On to step 1:
7 divided by 87 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 87

Moving on to step 2:
74 divided by 87 is 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 87

On to step 3:
When dividing 745 by 87, we get 8 with a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 696 from 745 to get 49.
Take the next digit (4) from the dividend and append it to 49, then repeat: 494 / 87

Let's proceed to step 4:
If we divide 494 by 87, we get 5 and a remainder of 59.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we subtract 435 from 494, we get 59.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 87

Moving on to step 5:
593 divided by 87 is 6 with a remainder of 71.
The number 6 becomes the next digit in our result. 
Result so far: 856.0
Subtracting 522 from 593 leaves us with 71.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 87

Step 6:
The number 87 fits into 714 8 times, leaving a remainder of 18.
The next digit of our result is 8. 
Result so far: 8568.0
If we take 696 away from 714, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
180 divided by 87 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 8568.2
Subtract 174 from 180 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
87 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 8568.2
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
87 can be fit into 600 6 times, resulting in a remainder of 78.
The next digit of our result is 6. 
Result so far: 8568.206
Subtracting 522 from 600 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 10:
780 divided by 87 is 8 with a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 8568.2068
Subtract 696 from 780 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 11:
If we divide 840 by 87, we get 9 and a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 8568.20689
Subtracting 783 from 840 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 12:
If we divide 570 by 87, we get 6 and a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 8568.206896
If we take 522 away from 570, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
The number 87 fits into 480 5 times, leaving a remainder of 45.
The next digit of our result is 5. 
Result so far: 8568.2068965
If we subtract 435 from 480, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
When dividing 450 by 87, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 8568.20689655
Subtracting 435 from 450 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 8568.20689655, with a leftover of 1.5e-08.
