We look at the division of 97959406 by 420 
Let's see how many times 420 fits into 97959406.

Let's proceed to step 1:
If we divide 9 by 420, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 420

Moving on to step 2:
420 goes into 97 0 times with a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Append the next digit (9) from the dividend to 97 and continue with: 979 / 420

On to step 3:
If we divide 979 by 420, we get 2 and a remainder of 139.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 139 after subtracting 840 from 979.
Take the next digit (5) from the dividend and append it to 139, then repeat: 1395 / 420

Step 4:
420 can be fit into 1395 3 times, resulting in a remainder of 135.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 1260 from 1395 leaves us with 135.
Include the next digit (9) from the dividend after 135, then repeat: 1359 / 420

Advancing to step 5:
If we divide 1359 by 420, we get 3 and a remainder of 99.
Write down 3 as next digit of the result. 
Result so far: 233.0
Deduct 1260 from 1359 and we're left with 99.
Grab the next digit (4) from the dividend, add it to 99, then carry on: 994 / 420

Advancing to step 6:
420 goes into 994 2 times with a remainder of 154.
The number 2 becomes the next digit in our result. 
Result so far: 2332.0
Subtract 840 from 994 to get 154.
Take the next digit (0) from the dividend and append it to 154, then repeat: 1540 / 420

Moving on to step 7:
When dividing 1540 by 420, we get 3 with a remainder of 280.
Use 3 as the next digit of our solution. 
Result so far: 23323.0
If we subtract 1260 from 1540, we get 280.
Fetch the next digit (6) from the dividend, attach it to 280 and continue: 2806 / 420

Going ahead to step 8:
420 goes into 2806 6 times with a remainder of 286.
Write down 6 as next digit of the result. 
Result so far: 233236.0
Deduct 2520 from 2806 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 9:
420 goes into 2860 6 times with a remainder of 340.
The number 6 becomes the next digit in our result. 
Result so far: 233236.6
If we subtract 2520 from 2860, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 10:
420 can be fit into 3400 8 times, resulting in a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 233236.68
Subtract 3360 from 3400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
When dividing 400 by 420, we get 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 233236.68
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 12:
420 goes into 4000 9 times with a remainder of 220.
The next digit of our result is 9. 
Result so far: 233236.6809
Subtracting 3780 from 4000 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 13:
420 goes into 2200 5 times with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 233236.68095
Subtract 2100 from 2200 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 14:
420 can be fit into 1000 2 times, resulting in a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 233236.680952
If we subtract 840 from 1000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 15:
The number 420 fits into 1600 3 times, leaving a remainder of 340.
The next digit of our result is 3. 
Result so far: 233236.6809523
The remainder is 340 after subtracting 1260 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 16:
3400 divided by 420 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 233236.68095238
If we take 3360 away from 3400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 233236.68095238, with a leftover of 4e-08.
