99970931 ÷ 236 
Let's see how many times 236 fits into 99970931.

Advancing to step 1:
236 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 236

Going ahead to step 2:
236 goes into 99 0 times with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Bring next digit (9) of the dividend behind the 99 and repeat the process: 999 / 236

On to step 3:
The number 236 fits into 999 4 times, leaving a remainder of 55.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 55 after subtracting 944 from 999.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 236

Advancing to step 4:
557 divided by 236 is 2 with a remainder of 85.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 472 away from 557, we end up with 85.
Bring next digit (0) of the dividend behind the 85 and repeat the process: 850 / 236

Let's proceed to step 5:
236 can be fit into 850 3 times, resulting in a remainder of 142.
Write down 3 as next digit of the result. 
Result so far: 423.0
If we subtract 708 from 850, we get 142.
Append the next digit (9) from the dividend to 142 and continue with: 1429 / 236

Going ahead to step 6:
The number 236 fits into 1429 6 times, leaving a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 4236.0
If we take 1416 away from 1429, we end up with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 236

Advancing to step 7:
When dividing 133 by 236, we get 0 with a remainder of 133.
The number 0 becomes the next digit in our result. 
Result so far: 42360.0
If we subtract 0 from 133, we get 133.
Bring next digit (1) of the dividend behind the 133 and repeat the process: 1331 / 236

Moving on to step 8:
236 goes into 1331 5 times with a remainder of 151.
Record the quotient 5 as the next digit in the result. 
Result so far: 423605.0
Subtract 1180 from 1331 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Advancing to step 9:
If we divide 1510 by 236, we get 6 and a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 423605.6
The remainder is 94 after subtracting 1416 from 1510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 10:
236 can be fit into 940 3 times, resulting in a remainder of 232.
Put 3 as the next digit of the answer. 
Result so far: 423605.63
If we subtract 708 from 940, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 11:
When dividing 2320 by 236, we get 9 with a remainder of 196.
Use 9 as the next digit of our solution. 
Result so far: 423605.639
If we take 2124 away from 2320, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 12:
When dividing 1960 by 236, we get 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 423605.6398
Subtracting 1888 from 1960 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
236 goes into 720 3 times with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 423605.63983
If we take 708 away from 720, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
120 divided by 236 is 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 423605.63983
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 15:
236 can be fit into 1200 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 423605.6398305
Subtracting 1180 from 1200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 16:
236 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 423605.6398305
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 423605.6398305 and a remainder of 2e-07.
