We look at the division of 99146645 by 709 
Let's see how many times 709 fits into 99146645.

Moving on to step 1:
When dividing 9 by 709, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 709

Advancing to step 2:
709 can be fit into 99 0 times, resulting in a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Include the next digit (1) from the dividend after 99, then repeat: 991 / 709

On to step 3:
The number 709 fits into 991 1 times, leaving a remainder of 282.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 709 away from 991, we end up with 282.
Fetch the next digit (4) from the dividend, attach it to 282 and continue: 2824 / 709

Advancing to step 4:
2824 divided by 709 is 3 with a remainder of 697.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 2127 from 2824 leaves us with 697.
Bring next digit (6) of the dividend behind the 697 and repeat the process: 6976 / 709

Advancing to step 5:
The number 709 fits into 6976 9 times, leaving a remainder of 595.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
If we subtract 6381 from 6976, we get 595.
Bring next digit (6) of the dividend behind the 595 and repeat the process: 5956 / 709

Advancing to step 6:
5956 divided by 709 is 8 with a remainder of 284.
Put 8 as the next digit of the answer. 
Result so far: 1398.0
Subtract 5672 from 5956 to get 284.
Bring next digit (4) of the dividend behind the 284 and repeat the process: 2844 / 709

Going ahead to step 7:
709 goes into 2844 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 13984.0
If we take 2836 away from 2844, we end up with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 709

On to step 8:
709 can be fit into 85 0 times, resulting in a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 139840.0
If we subtract 0 from 85, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 9:
709 can be fit into 850 1 times, resulting in a remainder of 141.
Put 1 as the next digit of the answer. 
Result so far: 139840.1
The remainder is 141 after subtracting 709 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 10:
The number 709 fits into 1410 1 times, leaving a remainder of 701.
Write down 1 as next digit of the result. 
Result so far: 139840.11
If we take 709 away from 1410, we end up with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

The quotient of the division is 139840.11, and the remainder is 0.701.
