We divide 84021424 by 207
We want to divide 84021424 by 207.

Going ahead to step 1:
8 divided by 207 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 207

Going ahead to step 2:
The number 207 fits into 84 0 times, leaving a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Grab the next digit (0) from the dividend, add it to 84, then carry on: 840 / 207

Going ahead to step 3:
If we divide 840 by 207, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 828 from 840 to get 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 207

Moving on to step 4:
207 can be fit into 122 0 times, resulting in a remainder of 122.
The next digit of our result is 0. 
Result so far: 40.0
The remainder is 122 after subtracting 0 from 122.
Take the next digit (1) from the dividend and append it to 122, then repeat: 1221 / 207

Going ahead to step 5:
When dividing 1221 by 207, we get 5 with a remainder of 186.
The next digit of our result is 5. 
Result so far: 405.0
Subtract 1035 from 1221 to get 186.
Grab the next digit (4) from the dividend, add it to 186, then carry on: 1864 / 207

Advancing to step 6:
The number 207 fits into 1864 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 4059.0
Subtract 1863 from 1864 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 207

Let's proceed to step 7:
207 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 40590.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 207

Moving on to step 8:
The number 207 fits into 124 0 times, leaving a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 405900.0
Subtract 0 from 124 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 9:
When dividing 1240 by 207, we get 5 with a remainder of 205.
Write down 5 as next digit of the result. 
Result so far: 405900.5
Subtracting 1035 from 1240 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 10:
207 goes into 2050 9 times with a remainder of 187.
Put 9 as the next digit of the answer. 
Result so far: 405900.59
The remainder is 187 after subtracting 1863 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 11:
The number 207 fits into 1870 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 405900.599
Deduct 1863 from 1870 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 405900.599 with a remaining 0.0007.
