We're dividing 70874309 by 742 
We want to divide 70874309 by 742.

On to step 1:
When dividing 7 by 742, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 742

Advancing to step 2:
If we divide 70 by 742, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Bring next digit (8) of the dividend behind the 70 and repeat the process: 708 / 742

Advancing to step 3:
The number 742 fits into 708 0 times, leaving a remainder of 708.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 708 after subtracting 0 from 708.
Grab the next digit (7) from the dividend, add it to 708, then carry on: 7087 / 742

Step 4:
If we divide 7087 by 742, we get 9 and a remainder of 409.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 6678 from 7087 leaves us with 409.
Bring next digit (4) of the dividend behind the 409 and repeat the process: 4094 / 742

Let's proceed to step 5:
When dividing 4094 by 742, we get 5 with a remainder of 384.
The next digit of our result is 5. 
Result so far: 95.0
The remainder is 384 after subtracting 3710 from 4094.
Take the next digit (3) from the dividend and append it to 384, then repeat: 3843 / 742

Advancing to step 6:
When dividing 3843 by 742, we get 5 with a remainder of 133.
Use 5 as the next digit of our solution. 
Result so far: 955.0
Deduct 3710 from 3843 and we're left with 133.
Take the next digit (0) from the dividend and append it to 133, then repeat: 1330 / 742

Let's proceed to step 7:
If we divide 1330 by 742, we get 1 and a remainder of 588.
Write down 1 as next digit of the result. 
Result so far: 9551.0
Subtract 742 from 1330 to get 588.
Bring next digit (9) of the dividend behind the 588 and repeat the process: 5889 / 742

Advancing to step 8:
The number 742 fits into 5889 7 times, leaving a remainder of 695.
Put 7 as the next digit of the answer. 
Result so far: 95517.0
Deduct 5194 from 5889 and we're left with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Moving on to step 9:
If we divide 6950 by 742, we get 9 and a remainder of 272.
Record the quotient 9 as the next digit in the result. 
Result so far: 95517.9
Subtract 6678 from 6950 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 10:
742 can be fit into 2720 3 times, resulting in a remainder of 494.
Record the quotient 3 as the next digit in the result. 
Result so far: 95517.93
If we subtract 2226 from 2720, we get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Going ahead to step 11:
4940 divided by 742 is 6 with a remainder of 488.
The number 6 becomes the next digit in our result. 
Result so far: 95517.936
Deduct 4452 from 4940 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 12:
The number 742 fits into 4880 6 times, leaving a remainder of 428.
The number 6 becomes the next digit in our result. 
Result so far: 95517.9366
Deduct 4452 from 4880 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

After the division, we end up with 95517.9366 and a remainder of 0.00428.
