We look at the division of 99606984 by 158 
We're looking to find how many times 158 goes into 99606984.

Advancing to step 1:
If we divide 9 by 158, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 158

Moving on to step 2:
158 goes into 99 0 times with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Include the next digit (6) from the dividend after 99, then repeat: 996 / 158

Let's proceed to step 3:
158 goes into 996 6 times with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 948 from 996 and we're left with 48.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 158

Going ahead to step 4:
480 divided by 158 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 63.0
The remainder is 6 after subtracting 474 from 480.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 158

On to step 5:
When dividing 66 by 158, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 630.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 158

Going ahead to step 6:
When dividing 669 by 158, we get 4 with a remainder of 37.
Write down 4 as next digit of the result. 
Result so far: 6304.0
The remainder is 37 after subtracting 632 from 669.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 158

On to step 7:
When dividing 378 by 158, we get 2 with a remainder of 62.
The next digit of our result is 2. 
Result so far: 63042.0
Subtract 316 from 378 to get 62.
Append the next digit (4) from the dividend to 62 and continue with: 624 / 158

Advancing to step 8:
624 divided by 158 is 3 with a remainder of 150.
Use 3 as the next digit of our solution. 
Result so far: 630423.0
Subtracting 474 from 624 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 9:
1500 divided by 158 is 9 with a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 630423.9
If we take 1422 away from 1500, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 10:
158 goes into 780 4 times with a remainder of 148.
Put 4 as the next digit of the answer. 
Result so far: 630423.94
Subtracting 632 from 780 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 11:
If we divide 1480 by 158, we get 9 and a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 630423.949
If we subtract 1422 from 1480, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
158 can be fit into 580 3 times, resulting in a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 630423.9493
Deduct 474 from 580 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 13:
1060 divided by 158 is 6 with a remainder of 112.
The next digit of our result is 6. 
Result so far: 630423.94936
If we take 948 away from 1060, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 14:
When dividing 1120 by 158, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 630423.949367
Subtract 1106 from 1120 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 15:
The number 158 fits into 140 0 times, leaving a remainder of 140.
The next digit of our result is 0. 
Result so far: 630423.949367
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 16:
1400 divided by 158 is 8 with a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 630423.94936708
If we take 1264 away from 1400, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The quotient of the division is 630423.94936708, and the remainder is 1.36e-07.
