We divide 70980054 by 643
We want to divide 70980054 by 643.

Advancing to step 1:
The number 643 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 643

Let's proceed to step 2:
643 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Fetch the next digit (9) from the dividend, attach it to 70 and continue: 709 / 643

Going ahead to step 3:
When dividing 709 by 643, we get 1 with a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 66 after subtracting 643 from 709.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 643

Advancing to step 4:
If we divide 668 by 643, we get 1 and a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 643 from 668 and we're left with 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 643

Moving on to step 5:
643 goes into 250 0 times with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 110.0
If we take 0 away from 250, we end up with 250.
Take the next digit (0) from the dividend and append it to 250, then repeat: 2500 / 643

On to step 6:
2500 divided by 643 is 3 with a remainder of 571.
The next digit of our result is 3. 
Result so far: 1103.0
If we take 1929 away from 2500, we end up with 571.
Grab the next digit (5) from the dividend, add it to 571, then carry on: 5715 / 643

Advancing to step 7:
5715 divided by 643 is 8 with a remainder of 571.
Use 8 as the next digit of our solution. 
Result so far: 11038.0
If we subtract 5144 from 5715, we get 571.
Fetch the next digit (4) from the dividend, attach it to 571 and continue: 5714 / 643

Let's proceed to step 8:
5714 divided by 643 is 8 with a remainder of 570.
The next digit of our result is 8. 
Result so far: 110388.0
If we take 5144 away from 5714, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Moving on to step 9:
If we divide 5700 by 643, we get 8 and a remainder of 556.
The number 8 becomes the next digit in our result. 
Result so far: 110388.8
Subtracting 5144 from 5700 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Advancing to step 10:
If we divide 5560 by 643, we get 8 and a remainder of 416.
Write down 8 as next digit of the result. 
Result so far: 110388.88
If we take 5144 away from 5560, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

After the division, we end up with 110388.88 and a remainder of 0.416.
