742723 ÷ 84 
We want to figure out the number of times 742723 can be divided by 84.

On to step 1:
84 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 84

Moving on to step 2:
84 goes into 74 0 times with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Grab the next digit (2) from the dividend, add it to 74, then carry on: 742 / 84

Step 3:
When dividing 742 by 84, we get 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 672 from 742 to get 70.
Fetch the next digit (7) from the dividend, attach it to 70 and continue: 707 / 84

Moving on to step 4:
707 divided by 84 is 8 with a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Subtracting 672 from 707 leaves us with 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 84

Moving on to step 5:
When dividing 352 by 84, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 884.0
If we take 336 away from 352, we end up with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 84

Going ahead to step 6:
163 divided by 84 is 1 with a remainder of 79.
The next digit of our result is 1. 
Result so far: 8841.0
Subtracting 84 from 163 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.

Advancing to step 7:
84 can be fit into 790 9 times, resulting in a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 8841.9
Subtract 756 from 790 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
If we divide 340 by 84, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 8841.94
The remainder is 4 after subtracting 336 from 340.
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 9:
40 divided by 84 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8841.94
Deduct 0 from 40 and we're left with 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 10:
84 goes into 400 4 times with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 8841.9404
Subtract 336 from 400 to 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.

Step 11:
84 can be fit into 640 7 times, resulting in a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 8841.94047
Deduct 588 from 640 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.

Moving on to step 12:
If we divide 520 by 84, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 8841.940476
Subtract 504 from 520 to 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.

Let's proceed to step 13:
84 goes into 160 1 times with a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 8841.9404761
Subtract 84 from 160 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
When dividing 760 by 84, we get 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 8841.94047619
Subtract 756 from 760 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.

The final outcome is 8841.94047619, with a leftover of 4e-09.
