We're dividing 70298143 by 305 
We want to divide 70298143 by 305.

Let's proceed to step 1:
305 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 305

Moving on to step 2:
If we divide 70 by 305, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Bring next digit (2) of the dividend behind the 70 and repeat the process: 702 / 305

Moving on to step 3:
702 divided by 305 is 2 with a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 610 from 702, we get 92.
Fetch the next digit (9) from the dividend, attach it to 92 and continue: 929 / 305

Moving on to step 4:
305 goes into 929 3 times with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 915 from 929, we get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 305

Going ahead to step 5:
148 divided by 305 is 0 with a remainder of 148.
Put 0 as the next digit of the answer. 
Result so far: 230.0
Subtracting 0 from 148 leaves us with 148.
Fetch the next digit (1) from the dividend, attach it to 148 and continue: 1481 / 305

Going ahead to step 6:
305 goes into 1481 4 times with a remainder of 261.
Write down 4 as next digit of the result. 
Result so far: 2304.0
If we subtract 1220 from 1481, we get 261.
Bring next digit (4) of the dividend behind the 261 and repeat the process: 2614 / 305

Let's proceed to step 7:
The number 305 fits into 2614 8 times, leaving a remainder of 174.
The next digit of our result is 8. 
Result so far: 23048.0
Deduct 2440 from 2614 and we're left with 174.
Append the next digit (3) from the dividend to 174 and continue with: 1743 / 305

On to step 8:
The number 305 fits into 1743 5 times, leaving a remainder of 218.
Use 5 as the next digit of our solution. 
Result so far: 230485.0
Subtracting 1525 from 1743 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 9:
305 goes into 2180 7 times with a remainder of 45.
The next digit of our result is 7. 
Result so far: 230485.7
If we take 2135 away from 2180, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
305 can be fit into 450 1 times, resulting in a remainder of 145.
The next digit of our result is 1. 
Result so far: 230485.71
Deduct 305 from 450 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 11:
If we divide 1450 by 305, we get 4 and a remainder of 230.
Use 4 as the next digit of our solution. 
Result so far: 230485.714
Subtract 1220 from 1450 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 12:
2300 divided by 305 is 7 with a remainder of 165.
Use 7 as the next digit of our solution. 
Result so far: 230485.7147
If we subtract 2135 from 2300, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 13:
305 can be fit into 1650 5 times, resulting in a remainder of 125.
The next digit of our result is 5. 
Result so far: 230485.71475
If we take 1525 away from 1650, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 14:
When dividing 1250 by 305, we get 4 with a remainder of 30.
The next digit of our result is 4. 
Result so far: 230485.714754
Subtract 1220 from 1250 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 15:
The number 305 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 230485.714754
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 16:
If we divide 3000 by 305, we get 9 and a remainder of 255.
Use 9 as the next digit of our solution. 
Result so far: 230485.71475409
If we subtract 2745 from 3000, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

The final result is 230485.71475409 with a remainder of 2.55e-07.
