We look at the division of 6351605 by 84 
We want to figure out the number of times 6351605 can be divided by 84.

Let's proceed to step 1:
When dividing 6 by 84, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 84

On to step 2:
If we divide 63 by 84, we get 0 and a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 84

Let's proceed to step 3:
The number 84 fits into 635 7 times, leaving a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 588 from 635 and we're left with 47.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 84

Let's proceed to step 4:
When dividing 471 by 84, we get 5 with a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
The remainder is 51 after subtracting 420 from 471.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 84

Going ahead to step 5:
The number 84 fits into 516 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 756.0
If we take 504 away from 516, we end up with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 84

Going ahead to step 6:
120 divided by 84 is 1 with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 7561.0
Subtracting 84 from 120 leaves us with 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 84

Advancing to step 7:
If we divide 365 by 84, we get 4 and a remainder of 29.
The next digit of our result is 4. 
Result so far: 75614.0
Subtract 336 from 365 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
If we divide 290 by 84, we get 3 and a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 75614.3
Subtract 252 from 290 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
84 can be fit into 380 4 times, resulting in a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 75614.34
If we take 336 away from 380, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
84 goes into 440 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 75614.345
If we take 420 away from 440, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
84 goes into 200 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 75614.3452
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
84 can be fit into 320 3 times, resulting in a remainder of 68.
The next digit of our result is 3. 
Result so far: 75614.34523
Deduct 252 from 320 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 13:
84 goes into 680 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 75614.345238
Subtracting 672 from 680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
84 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 75614.345238
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 15:
If we divide 800 by 84, we get 9 and a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 75614.34523809
If we take 756 away from 800, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 75614.34523809, with a leftover of 4.4e-08.
