99670628 ÷ 816 
We want to divide 99670628 by 816.

Going ahead to step 1:
816 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 816

Advancing to step 2:
816 goes into 99 0 times with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Bring next digit (6) of the dividend behind the 99 and repeat the process: 996 / 816

On to step 3:
996 divided by 816 is 1 with a remainder of 180.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 816 away from 996, we end up with 180.
Grab the next digit (7) from the dividend, add it to 180, then carry on: 1807 / 816

Step 4:
If we divide 1807 by 816, we get 2 and a remainder of 175.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1632 from 1807 leaves us with 175.
Include the next digit (0) from the dividend after 175, then repeat: 1750 / 816

On to step 5:
When dividing 1750 by 816, we get 2 with a remainder of 118.
Use 2 as the next digit of our solution. 
Result so far: 122.0
If we subtract 1632 from 1750, we get 118.
Bring next digit (6) of the dividend behind the 118 and repeat the process: 1186 / 816

On to step 6:
The number 816 fits into 1186 1 times, leaving a remainder of 370.
The number 1 becomes the next digit in our result. 
Result so far: 1221.0
Subtracting 816 from 1186 leaves us with 370.
Take the next digit (2) from the dividend and append it to 370, then repeat: 3702 / 816

Step 7:
816 can be fit into 3702 4 times, resulting in a remainder of 438.
Record the quotient 4 as the next digit in the result. 
Result so far: 12214.0
If we subtract 3264 from 3702, we get 438.
Include the next digit (8) from the dividend after 438, then repeat: 4388 / 816

Step 8:
If we divide 4388 by 816, we get 5 and a remainder of 308.
The next digit of our result is 5. 
Result so far: 122145.0
The remainder is 308 after subtracting 4080 from 4388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 9:
The number 816 fits into 3080 3 times, leaving a remainder of 632.
Write down 3 as next digit of the result. 
Result so far: 122145.3
If we subtract 2448 from 3080, we get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 10:
The number 816 fits into 6320 7 times, leaving a remainder of 608.
Use 7 as the next digit of our solution. 
Result so far: 122145.37
If we take 5712 away from 6320, we end up with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Moving on to step 11:
If we divide 6080 by 816, we get 7 and a remainder of 368.
Write down 7 as next digit of the result. 
Result so far: 122145.377
If we subtract 5712 from 6080, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Our division results in 122145.377 with a remaining 0.0368.
