We're dividing 71117636 by 420 
Let's see how many times 420 fits into 71117636.

Going ahead to step 1:
When dividing 7 by 420, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 420

Advancing to step 2:
420 goes into 71 0 times with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Fetch the next digit (1) from the dividend, attach it to 71 and continue: 711 / 420

Step 3:
420 goes into 711 1 times with a remainder of 291.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 420 from 711 to get 291.
Include the next digit (1) from the dividend after 291, then repeat: 2911 / 420

Going ahead to step 4:
The number 420 fits into 2911 6 times, leaving a remainder of 391.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 2520 from 2911 to get 391.
Fetch the next digit (7) from the dividend, attach it to 391 and continue: 3917 / 420

Advancing to step 5:
3917 divided by 420 is 9 with a remainder of 137.
Put 9 as the next digit of the answer. 
Result so far: 169.0
If we take 3780 away from 3917, we end up with 137.
Bring next digit (6) of the dividend behind the 137 and repeat the process: 1376 / 420

Advancing to step 6:
If we divide 1376 by 420, we get 3 and a remainder of 116.
The number 3 becomes the next digit in our result. 
Result so far: 1693.0
If we subtract 1260 from 1376, we get 116.
Append the next digit (3) from the dividend to 116 and continue with: 1163 / 420

Going ahead to step 7:
1163 divided by 420 is 2 with a remainder of 323.
Use 2 as the next digit of our solution. 
Result so far: 16932.0
The remainder is 323 after subtracting 840 from 1163.
Include the next digit (6) from the dividend after 323, then repeat: 3236 / 420

Going ahead to step 8:
The number 420 fits into 3236 7 times, leaving a remainder of 296.
Put 7 as the next digit of the answer. 
Result so far: 169327.0
Subtract 2940 from 3236 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 9:
420 can be fit into 2960 7 times, resulting in a remainder of 20.
The next digit of our result is 7. 
Result so far: 169327.7
Deduct 2940 from 2960 and we're left 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.

Step 10:
420 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 169327.7
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
When dividing 2000 by 420, we get 4 with a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 169327.704
Subtract 1680 from 2000 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 12:
If we divide 3200 by 420, we get 7 and a remainder of 260.
The number 7 becomes the next digit in our result. 
Result so far: 169327.7047
The remainder is 260 after subtracting 2940 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 13:
When dividing 2600 by 420, we get 6 with a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 169327.70476
Subtracting 2520 from 2600 leaves us 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.

Let's proceed to step 14:
800 divided by 420 is 1 with a remainder of 380.
Put 1 as the next digit of the answer. 
Result so far: 169327.704761
If we take 420 away from 800, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 15:
420 can be fit into 3800 9 times, resulting in a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 169327.7047619
Subtracting 3780 from 3800 leaves us 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.

Going ahead to step 16:
200 divided by 420 is 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 169327.7047619
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 169327.7047619 with a remainder of 2e-07.
