We look at the division of 99689910 by 438 
We want to divide 99689910 by 438.

Step 1:
If we divide 9 by 438, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 438

Going ahead to step 2:
438 can be fit into 99 0 times, resulting in a remainder of 99.
Use 0 as the next digit of our solution. 
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 / 438

Advancing to step 3:
When dividing 996 by 438, we get 2 with a remainder of 120.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 120 after subtracting 876 from 996.
Grab the next digit (8) from the dividend, add it to 120, then carry on: 1208 / 438

Step 4:
If we divide 1208 by 438, we get 2 and a remainder of 332.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 876 from 1208 to get 332.
Append the next digit (9) from the dividend to 332 and continue with: 3329 / 438

Moving on to step 5:
If we divide 3329 by 438, we get 7 and a remainder of 263.
The next digit of our result is 7. 
Result so far: 227.0
The remainder is 263 after subtracting 3066 from 3329.
Fetch the next digit (9) from the dividend, attach it to 263 and continue: 2639 / 438

Moving on to step 6:
When dividing 2639 by 438, we get 6 with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 2276.0
Deduct 2628 from 2639 and we're left with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 438

Moving on to step 7:
If we divide 111 by 438, we get 0 and a remainder of 111.
The next digit of our result is 0. 
Result so far: 22760.0
Subtract 0 from 111 to get 111.
Bring next digit (0) of the dividend behind the 111 and repeat the process: 1110 / 438

Moving on to step 8:
The number 438 fits into 1110 2 times, leaving a remainder of 234.
Use 2 as the next digit of our solution. 
Result so far: 227602.0
Subtracting 876 from 1110 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 9:
The number 438 fits into 2340 5 times, leaving a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 227602.5
The remainder is 150 after subtracting 2190 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
438 can be fit into 1500 3 times, resulting in a remainder of 186.
The number 3 becomes the next digit in our result. 
Result so far: 227602.53
Subtracting 1314 from 1500 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 11:
The number 438 fits into 1860 4 times, leaving a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 227602.534
Subtracting 1752 from 1860 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 12:
If we divide 1080 by 438, we get 2 and a remainder of 204.
Write down 2 as next digit of the result. 
Result so far: 227602.5342
If we subtract 876 from 1080, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 13:
438 can be fit into 2040 4 times, resulting in a remainder of 288.
Use 4 as the next digit of our solution. 
Result so far: 227602.53424
If we take 1752 away from 2040, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 14:
The number 438 fits into 2880 6 times, leaving a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 227602.534246
The remainder is 252 after subtracting 2628 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 15:
438 can be fit into 2520 5 times, resulting in a remainder of 330.
Write down 5 as next digit of the result. 
Result so far: 227602.5342465
If we subtract 2190 from 2520, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 16:
438 goes into 3300 7 times with a remainder of 234.
Write down 7 as next digit of the result. 
Result so far: 227602.53424657
If we subtract 3066 from 3300, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

The quotient of the division is 227602.53424657, and the remainder is 2.34e-07.
