We look at the division of 70370999 by 671 
Let's see how many times 671 fits into 70370999.

On to step 1:
When dividing 7 by 671, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 671

Step 2:
When dividing 70 by 671, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 671

Advancing to step 3:
If we divide 703 by 671, we get 1 and a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 671 away from 703, we end up with 32.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 671

Moving on to step 4:
When dividing 327 by 671, we get 0 with a remainder of 327.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 327 after subtracting 0 from 327.
Append the next digit (0) from the dividend to 327 and continue with: 3270 / 671

Moving on to step 5:
3270 divided by 671 is 4 with a remainder of 586.
The next digit of our result is 4. 
Result so far: 104.0
If we subtract 2684 from 3270, we get 586.
Grab the next digit (9) from the dividend, add it to 586, then carry on: 5869 / 671

Let's proceed to step 6:
671 can be fit into 5869 8 times, resulting in a remainder of 501.
Use 8 as the next digit of our solution. 
Result so far: 1048.0
If we subtract 5368 from 5869, we get 501.
Append the next digit (9) from the dividend to 501 and continue with: 5019 / 671

Moving on to step 7:
5019 divided by 671 is 7 with a remainder of 322.
Use 7 as the next digit of our solution. 
Result so far: 10487.0
If we subtract 4697 from 5019, we get 322.
Include the next digit (9) from the dividend after 322, then repeat: 3229 / 671

Moving on to step 8:
If we divide 3229 by 671, we get 4 and a remainder of 545.
Use 4 as the next digit of our solution. 
Result so far: 104874.0
If we take 2684 away from 3229, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Advancing to step 9:
When dividing 5450 by 671, we get 8 with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 104874.8
Subtracting 5368 from 5450 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 10:
If we divide 820 by 671, we get 1 and a remainder of 149.
Put 1 as the next digit of the answer. 
Result so far: 104874.81
If we subtract 671 from 820, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 11:
The number 671 fits into 1490 2 times, leaving a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 104874.812
Deduct 1342 from 1490 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 12:
If we divide 1480 by 671, we get 2 and a remainder of 138.
Put 2 as the next digit of the answer. 
Result so far: 104874.8122
If we subtract 1342 from 1480, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The quotient of the division is 104874.8122, and the remainder is 0.00138.
