70471575 ÷ 421 
We're looking to find how many times 421 goes into 70471575.

Going ahead to step 1:
421 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 421

On to step 2:
421 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Append the next digit (4) from the dividend to 70 and continue with: 704 / 421

Moving on to step 3:
421 goes into 704 1 times with a remainder of 283.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 283 after subtracting 421 from 704.
Grab the next digit (7) from the dividend, add it to 283, then carry on: 2837 / 421

Going ahead to step 4:
When dividing 2837 by 421, we get 6 with a remainder of 311.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 311 after subtracting 2526 from 2837.
Take the next digit (1) from the dividend and append it to 311, then repeat: 3111 / 421

Let's proceed to step 5:
The number 421 fits into 3111 7 times, leaving a remainder of 164.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
If we take 2947 away from 3111, we end up with 164.
Bring next digit (5) of the dividend behind the 164 and repeat the process: 1645 / 421

Moving on to step 6:
1645 divided by 421 is 3 with a remainder of 382.
Write down 3 as next digit of the result. 
Result so far: 1673.0
If we take 1263 away from 1645, we end up with 382.
Include the next digit (7) from the dividend after 382, then repeat: 3827 / 421

Step 7:
The number 421 fits into 3827 9 times, leaving a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 16739.0
If we subtract 3789 from 3827, we get 38.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 421

Moving on to step 8:
385 divided by 421 is 0 with a remainder of 385.
The number 0 becomes the next digit in our result. 
Result so far: 167390.0
Subtracting 0 from 385 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 9:
421 goes into 3850 9 times with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 167390.9
The remainder is 61 after subtracting 3789 from 3850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 10:
610 divided by 421 is 1 with a remainder of 189.
Write down 1 as next digit of the result. 
Result so far: 167390.91
If we take 421 away from 610, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Moving on to step 11:
421 can be fit into 1890 4 times, resulting in a remainder of 206.
The next digit of our result is 4. 
Result so far: 167390.914
Subtract 1684 from 1890 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 12:
421 can be fit into 2060 4 times, resulting in a remainder of 376.
Record the quotient 4 as the next digit in the result. 
Result so far: 167390.9144
Subtract 1684 from 2060 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

After the division, we end up with 167390.9144 and a remainder of 0.00376.
