We divide 70297313 by 643
Our goal is to divide 70297313 by 643.

Step 1:
643 goes into 7 0 times with 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 / 643

Let's proceed to step 2:
643 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Bring next digit (2) of the dividend behind the 70 and repeat the process: 702 / 643

Moving on to step 3:
702 divided by 643 is 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 643 from 702 to get 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 643

Step 4:
The number 643 fits into 599 0 times, leaving a remainder of 599.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 599 to get 599.
Append the next digit (7) from the dividend to 599 and continue with: 5997 / 643

Going ahead to step 5:
If we divide 5997 by 643, we get 9 and a remainder of 210.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Subtract 5787 from 5997 to get 210.
Append the next digit (3) from the dividend to 210 and continue with: 2103 / 643

Moving on to step 6:
643 goes into 2103 3 times with a remainder of 174.
Write down 3 as next digit of the result. 
Result so far: 1093.0
If we subtract 1929 from 2103, we get 174.
Fetch the next digit (1) from the dividend, attach it to 174 and continue: 1741 / 643

On to step 7:
The number 643 fits into 1741 2 times, leaving a remainder of 455.
Write down 2 as next digit of the result. 
Result so far: 10932.0
Subtract 1286 from 1741 to get 455.
Bring next digit (3) of the dividend behind the 455 and repeat the process: 4553 / 643

Let's proceed to step 8:
When dividing 4553 by 643, we get 7 with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 109327.0
The remainder is 52 after subtracting 4501 from 4553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
520 divided by 643 is 0 with a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 109327.0
Deduct 0 from 520 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 10:
The number 643 fits into 5200 8 times, leaving a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 109327.08
If we subtract 5144 from 5200, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
When dividing 560 by 643, we get 0 with a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 109327.08
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 12:
643 goes into 5600 8 times with a remainder of 456.
Record the quotient 8 as the next digit in the result. 
Result so far: 109327.0808
Subtract 5144 from 5600 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 13:
4560 divided by 643 is 7 with a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 109327.08087
Subtract 4501 from 4560 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 14:
643 can be fit into 590 0 times, resulting in a remainder of 590.
The next digit of our result is 0. 
Result so far: 109327.08087
The remainder is 590 after subtracting 0 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 15:
643 can be fit into 5900 9 times, resulting in a remainder of 113.
Write down 9 as next digit of the result. 
Result so far: 109327.0808709
Subtract 5787 from 5900 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 16:
If we divide 1130 by 643, we get 1 and a remainder of 487.
Put 1 as the next digit of the answer. 
Result so far: 109327.08087091
Subtract 643 from 1130 to get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

After the division, we end up with 109327.08087091 and a remainder of 4.87e-07.
