We look at the division of 76841447 by 420 
Let's see how many times 420 fits into 76841447.

Advancing to step 1:
If we divide 7 by 420, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 420

On to step 2:
420 goes into 76 0 times with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Append the next digit (8) from the dividend to 76 and continue with: 768 / 420

Let's proceed to step 3:
The number 420 fits into 768 1 times, leaving a remainder of 348.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 420 from 768, we get 348.
Take the next digit (4) from the dividend and append it to 348, then repeat: 3484 / 420

Going ahead to step 4:
420 can be fit into 3484 8 times, resulting in a remainder of 124.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 124 after subtracting 3360 from 3484.
Take the next digit (1) from the dividend and append it to 124, then repeat: 1241 / 420

On to step 5:
1241 divided by 420 is 2 with a remainder of 401.
Write down 2 as next digit of the result. 
Result so far: 182.0
The remainder is 401 after subtracting 840 from 1241.
Bring next digit (4) of the dividend behind the 401 and repeat the process: 4014 / 420

Moving on to step 6:
If we divide 4014 by 420, we get 9 and a remainder of 234.
Put 9 as the next digit of the answer. 
Result so far: 1829.0
The remainder is 234 after subtracting 3780 from 4014.
Take the next digit (4) from the dividend and append it to 234, then repeat: 2344 / 420

Step 7:
420 goes into 2344 5 times with a remainder of 244.
The next digit of our result is 5. 
Result so far: 18295.0
Deduct 2100 from 2344 and we're left with 244.
Append the next digit (7) from the dividend to 244 and continue with: 2447 / 420

Going ahead to step 8:
420 can be fit into 2447 5 times, resulting in a remainder of 347.
Use 5 as the next digit of our solution. 
Result so far: 182955.0
If we subtract 2100 from 2447, we get 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 9:
When dividing 3470 by 420, we get 8 with a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 182955.8
If we subtract 3360 from 3470, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 10:
The number 420 fits into 1100 2 times, leaving a remainder of 260.
The number 2 becomes the next digit in our result. 
Result so far: 182955.82
If we subtract 840 from 1100, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 11:
420 goes into 2600 6 times with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 182955.826
If we subtract 2520 from 2600, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
When dividing 800 by 420, we get 1 with a remainder of 380.
Record the quotient 1 as the next digit in the result. 
Result so far: 182955.8261
If we subtract 420 from 800, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 13:
420 goes into 3800 9 times with a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 182955.82619
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.

On to step 14:
420 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 182955.82619
If we take 0 away from 200, we end up 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.

On to step 15:
The number 420 fits into 2000 4 times, leaving a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 182955.8261904
If we take 1680 away from 2000, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 16:
The number 420 fits into 3200 7 times, leaving a remainder of 260.
The next digit of our result is 7. 
Result so far: 182955.82619047
If we subtract 2940 from 3200, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 182955.82619047, with a leftover of 2.6e-07.
