Let's divide 451207 by 84
We're looking to find how many times 84 goes into 451207.

On to step 1:
84 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 84

Advancing to step 2:
84 goes into 45 0 times with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 84

Advancing to step 3:
When dividing 451 by 84, we get 5 with a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 420 from 451 leaves us with 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 84

Moving on to step 4:
If we divide 312 by 84, we get 3 and a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtract 252 from 312 to get 60.
Grab the next digit (0) from the dividend, add it to 60, then carry on: 600 / 84

Let's proceed to step 5:
600 divided by 84 is 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 537.0
If we subtract 588 from 600, we get 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 84

Advancing to step 6:
84 can be fit into 127 1 times, resulting in a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 5371.0
If we subtract 84 from 127, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
430 divided by 84 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5371.5
The remainder is 10 after subtracting 420 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
84 can be fit into 100 1 times, resulting in a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 5371.51
If we subtract 84 from 100, 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 9:
If we divide 160 by 84, we get 1 and a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 5371.511
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.

The final result is 5371.511 with a remainder of 0.0076.
