We divide 99747979 by 800
We want to divide 99747979 by 800.

Let's proceed to step 1:
If we divide 9 by 800, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 800

Let's proceed to step 2:
If we divide 99 by 800, we get 0 and a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Bring next digit (7) of the dividend behind the 99 and repeat the process: 997 / 800

Step 3:
When dividing 997 by 800, we get 1 with a remainder of 197.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 800 away from 997, we end up with 197.
Grab the next digit (4) from the dividend, add it to 197, then carry on: 1974 / 800

Step 4:
800 can be fit into 1974 2 times, resulting in a remainder of 374.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1600 from 1974 to get 374.
Fetch the next digit (7) from the dividend, attach it to 374 and continue: 3747 / 800

Step 5:
800 can be fit into 3747 4 times, resulting in a remainder of 547.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
The remainder is 547 after subtracting 3200 from 3747.
Fetch the next digit (9) from the dividend, attach it to 547 and continue: 5479 / 800

Going ahead to step 6:
When dividing 5479 by 800, we get 6 with a remainder of 679.
Use 6 as the next digit of our solution. 
Result so far: 1246.0
Deduct 4800 from 5479 and we're left with 679.
Take the next digit (7) from the dividend and append it to 679, then repeat: 6797 / 800

Advancing to step 7:
If we divide 6797 by 800, we get 8 and a remainder of 397.
Use 8 as the next digit of our solution. 
Result so far: 12468.0
Subtract 6400 from 6797 to get 397.
Append the next digit (9) from the dividend to 397 and continue with: 3979 / 800

Advancing to step 8:
If we divide 3979 by 800, we get 4 and a remainder of 779.
Put 4 as the next digit of the answer. 
Result so far: 124684.0
If we subtract 3200 from 3979, we get 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

On to step 9:
If we divide 7790 by 800, we get 9 and a remainder of 590.
The number 9 becomes the next digit in our result. 
Result so far: 124684.9
Deduct 7200 from 7790 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 10:
The number 800 fits into 5900 7 times, leaving a remainder of 300.
Record the quotient 7 as the next digit in the result. 
Result so far: 124684.97
Subtracting 5600 from 5900 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
800 can be fit into 3000 3 times, resulting in a remainder of 600.
Use 3 as the next digit of our solution. 
Result so far: 124684.973
Deduct 2400 from 3000 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 12:
If we divide 6000 by 800, we get 7 and a remainder of 400.
The next digit of our result is 7. 
Result so far: 124684.9737
Deduct 5600 from 6000 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
800 goes into 4000 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 124684.97375
If we take 4000 away from 4000, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 14:
0 divided by 800 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 124684.97375
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 15:
If we divide 0 by 800, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 124684.97375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 124684.97375, and the remainder is 0.0.
