We're dividing 36140615 by 420 
We want to figure out the number of times 36140615 can be divided by 420.

Going ahead to step 1:
The number 420 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 420

On to step 2:
When dividing 36 by 420, we get 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 420

Let's proceed to step 3:
When dividing 361 by 420, we get 0 with a remainder of 361.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 361, we end up with 361.
Grab the next digit (4) from the dividend, add it to 361, then carry on: 3614 / 420

On to step 4:
When dividing 3614 by 420, we get 8 with a remainder of 254.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 3360 from 3614 to get 254.
Fetch the next digit (0) from the dividend, attach it to 254 and continue: 2540 / 420

Going ahead to step 5:
2540 divided by 420 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 86.0
The remainder is 20 after subtracting 2520 from 2540.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 420

Going ahead to step 6:
If we divide 206 by 420, we get 0 and a remainder of 206.
The next digit of our result is 0. 
Result so far: 860.0
The remainder is 206 after subtracting 0 from 206.
Fetch the next digit (1) from the dividend, attach it to 206 and continue: 2061 / 420

Advancing to step 7:
420 goes into 2061 4 times with a remainder of 381.
Put 4 as the next digit of the answer. 
Result so far: 8604.0
If we subtract 1680 from 2061, we get 381.
Take the next digit (5) from the dividend and append it to 381, then repeat: 3815 / 420

Moving on to step 8:
When dividing 3815 by 420, we get 9 with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 86049.0
If we subtract 3780 from 3815, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
The number 420 fits into 350 0 times, leaving a remainder of 350.
The next digit of our result is 0. 
Result so far: 86049.0
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 10:
420 goes into 3500 8 times with a remainder of 140.
Write down 8 as next digit of the result. 
Result so far: 86049.08
The remainder is 140 after subtracting 3360 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 11:
420 can be fit into 1400 3 times, resulting in a remainder of 140.
Write down 3 as next digit of the result. 
Result so far: 86049.083
Deduct 1260 from 1400 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 12:
If we divide 1400 by 420, we get 3 and a remainder of 140.
Record the quotient 3 as the next digit in the result. 
Result so far: 86049.0833
If we take 1260 away from 1400, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final outcome is 86049.0833, with a leftover of 0.0014.
