We look at the division of 70213221 by 583 
We're looking to find how many times 583 goes into 70213221.

On to step 1:
7 divided by 583 is 0 with 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.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 583

Step 2:
70 divided by 583 is 0 with 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.
Append the next digit (2) from the dividend to 70 and continue with: 702 / 583

Step 3:
The number 583 fits into 702 1 times, leaving a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 583 from 702, we get 119.
Include the next digit (1) from the dividend after 119, then repeat: 1191 / 583

On to step 4:
The number 583 fits into 1191 2 times, leaving a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 1166 from 1191 to get 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 583

Let's proceed to step 5:
583 goes into 253 0 times with a remainder of 253.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
The remainder is 253 after subtracting 0 from 253.
Take the next digit (2) from the dividend and append it to 253, then repeat: 2532 / 583

On to step 6:
When dividing 2532 by 583, we get 4 with a remainder of 200.
Use 4 as the next digit of our solution. 
Result so far: 1204.0
If we subtract 2332 from 2532, we get 200.
Fetch the next digit (2) from the dividend, attach it to 200 and continue: 2002 / 583

On to step 7:
583 goes into 2002 3 times with a remainder of 253.
The number 3 becomes the next digit in our result. 
Result so far: 12043.0
The remainder is 253 after subtracting 1749 from 2002.
Bring next digit (1) of the dividend behind the 253 and repeat the process: 2531 / 583

Moving on to step 8:
When dividing 2531 by 583, we get 4 with a remainder of 199.
Write down 4 as next digit of the result. 
Result so far: 120434.0
Subtract 2332 from 2531 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 9:
The number 583 fits into 1990 3 times, leaving a remainder of 241.
The number 3 becomes the next digit in our result. 
Result so far: 120434.3
If we take 1749 away from 1990, we end up with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 10:
The number 583 fits into 2410 4 times, leaving a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 120434.34
Deduct 2332 from 2410 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 11:
583 goes into 780 1 times with a remainder of 197.
The next digit of our result is 1. 
Result so far: 120434.341
If we take 583 away from 780, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 12:
583 can be fit into 1970 3 times, resulting in a remainder of 221.
The next digit of our result is 3. 
Result so far: 120434.3413
The remainder is 221 after subtracting 1749 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 13:
583 can be fit into 2210 3 times, resulting in a remainder of 461.
The number 3 becomes the next digit in our result. 
Result so far: 120434.34133
Subtract 1749 from 2210 to get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

The final outcome is 120434.34133, with a leftover of 0.000461.
