We're dividing 74512 by 84 
We want to figure out the number of times 74512 can be divided by 84.

Step 1:
If we divide 7 by 84, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 84

On to step 2:
74 divided by 84 is 0 with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Bring next digit (5) of the dividend behind the 74 and repeat the process: 745 / 84

Advancing to step 3:
The number 84 fits into 745 8 times, leaving a remainder of 73.
The next digit of our result is 8. 
Result so far: 8.0
If we take 672 away from 745, we end up with 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 84

Let's proceed to step 4:
If we divide 731 by 84, we get 8 and a remainder of 59.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Deduct 672 from 731 and we're left with 59.
Bring next digit (2) of the dividend behind the 59 and repeat the process: 592 / 84

On to step 5:
The number 84 fits into 592 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 887.0
Subtracting 588 from 592 leaves us with 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 6:
When dividing 40 by 84, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 887.0
If we subtract 0 from 40, we 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.

Advancing to step 7:
When dividing 400 by 84, we get 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 887.04
Subtracting 336 from 400 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
84 can be fit into 640 7 times, resulting in a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 887.047
Subtracting 588 from 640 leaves us 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 9:
520 divided by 84 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 887.0476
If we subtract 504 from 520, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
160 divided by 84 is 1 with a remainder of 76.
The next digit of our result is 1. 
Result so far: 887.04761
Subtracting 84 from 160 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
760 divided by 84 is 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 887.047619
If we take 756 away from 760, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
84 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 887.047619
If we subtract 0 from 40, we 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.

Step 13:
400 divided by 84 is 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 887.04761904
If we subtract 336 from 400, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 887.04761904 and a remainder of 6.4e-08.
