Let's divide 70405373 by 989
We want to divide 70405373 by 989.

On to step 1:
When dividing 7 by 989, we get 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.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 989

Going ahead to step 2:
The number 989 fits into 70 0 times, leaving 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.
Append the next digit (4) from the dividend to 70 and continue with: 704 / 989

On to step 3:
989 goes into 704 0 times with a remainder of 704.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 704, we end up with 704.
Append the next digit (0) from the dividend to 704 and continue with: 7040 / 989

Advancing to step 4:
When dividing 7040 by 989, we get 7 with a remainder of 117.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 6923 away from 7040, we end up with 117.
Grab the next digit (5) from the dividend, add it to 117, then carry on: 1175 / 989

Moving on to step 5:
989 goes into 1175 1 times with a remainder of 186.
Write down 1 as next digit of the result. 
Result so far: 71.0
Subtracting 989 from 1175 leaves us with 186.
Grab the next digit (3) from the dividend, add it to 186, then carry on: 1863 / 989

Moving on to step 6:
1863 divided by 989 is 1 with a remainder of 874.
Write down 1 as next digit of the result. 
Result so far: 711.0
If we subtract 989 from 1863, we get 874.
Fetch the next digit (7) from the dividend, attach it to 874 and continue: 8747 / 989

Moving on to step 7:
989 can be fit into 8747 8 times, resulting in a remainder of 835.
The number 8 becomes the next digit in our result. 
Result so far: 7118.0
If we subtract 7912 from 8747, we get 835.
Bring next digit (3) of the dividend behind the 835 and repeat the process: 8353 / 989

On to step 8:
989 can be fit into 8353 8 times, resulting in a remainder of 441.
Write down 8 as next digit of the result. 
Result so far: 71188.0
Deduct 7912 from 8353 and we're left with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Moving on to step 9:
When dividing 4410 by 989, we get 4 with a remainder of 454.
Use 4 as the next digit of our solution. 
Result so far: 71188.4
If we subtract 3956 from 4410, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Moving on to step 10:
4540 divided by 989 is 4 with a remainder of 584.
Use 4 as the next digit of our solution. 
Result so far: 71188.44
If we subtract 3956 from 4540, we get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

The quotient of the division is 71188.44, and the remainder is 0.584.
