70545239 ÷ 420 
Let's see how many times 420 fits into 70545239.

Going ahead to step 1:
The number 420 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 420

Advancing to step 2:
If we divide 70 by 420, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Fetch the next digit (5) from the dividend, attach it to 70 and continue: 705 / 420

Advancing to step 3:
When dividing 705 by 420, we get 1 with a remainder of 285.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 420 from 705, we get 285.
Take the next digit (4) from the dividend and append it to 285, then repeat: 2854 / 420

Going ahead to step 4:
420 goes into 2854 6 times with a remainder of 334.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 2520 from 2854, we get 334.
Append the next digit (5) from the dividend to 334 and continue with: 3345 / 420

On to step 5:
When dividing 3345 by 420, we get 7 with a remainder of 405.
The number 7 becomes the next digit in our result. 
Result so far: 167.0
Deduct 2940 from 3345 and we're left with 405.
Grab the next digit (2) from the dividend, add it to 405, then carry on: 4052 / 420

Step 6:
If we divide 4052 by 420, we get 9 and a remainder of 272.
The next digit of our result is 9. 
Result so far: 1679.0
Subtracting 3780 from 4052 leaves us with 272.
Append the next digit (3) from the dividend to 272 and continue with: 2723 / 420

Moving on to step 7:
2723 divided by 420 is 6 with a remainder of 203.
Write down 6 as next digit of the result. 
Result so far: 16796.0
If we take 2520 away from 2723, we end up with 203.
Grab the next digit (9) from the dividend, add it to 203, then carry on: 2039 / 420

Step 8:
The number 420 fits into 2039 4 times, leaving a remainder of 359.
Record the quotient 4 as the next digit in the result. 
Result so far: 167964.0
Subtract 1680 from 2039 to get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 9:
3590 divided by 420 is 8 with a remainder of 230.
Record the quotient 8 as the next digit in the result. 
Result so far: 167964.8
If we take 3360 away from 3590, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 10:
When dividing 2300 by 420, we get 5 with a remainder of 200.
The next digit of our result is 5. 
Result so far: 167964.85
Subtracting 2100 from 2300 leaves us 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.

Going ahead to step 11:
If we divide 2000 by 420, we get 4 and a remainder of 320.
The next digit of our result is 4. 
Result so far: 167964.854
The remainder is 320 after subtracting 1680 from 2000.
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 next digit of our result is 7. 
Result so far: 167964.8547
Deduct 2940 from 3200 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 13:
The number 420 fits into 2600 6 times, leaving a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 167964.85476
Deduct 2520 from 2600 and we're left 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.

Step 14:
420 goes into 800 1 times with a remainder of 380.
The number 1 becomes the next digit in our result. 
Result so far: 167964.854761
The remainder is 380 after subtracting 420 from 800.
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:
The number 420 fits into 3800 9 times, leaving a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 167964.8547619
If we take 3780 away from 3800, we end up 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.

Moving on to step 16:
200 divided by 420 is 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 167964.8547619
Subtract 0 from 200 to get 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 quotient of the division is 167964.8547619, and the remainder is 2e-07.
