97770065 ÷ 438 
Let's see how many times 438 fits into 97770065.

Advancing to step 1:
When dividing 9 by 438, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 438

Step 2:
The number 438 fits into 97 0 times, leaving a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Append the next digit (7) from the dividend to 97 and continue with: 977 / 438

Moving on to step 3:
438 can be fit into 977 2 times, resulting in a remainder of 101.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 876 from 977 and we're left with 101.
Fetch the next digit (7) from the dividend, attach it to 101 and continue: 1017 / 438

Step 4:
The number 438 fits into 1017 2 times, leaving a remainder of 141.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 876 from 1017 to get 141.
Bring next digit (0) of the dividend behind the 141 and repeat the process: 1410 / 438

On to step 5:
If we divide 1410 by 438, we get 3 and a remainder of 96.
The number 3 becomes the next digit in our result. 
Result so far: 223.0
The remainder is 96 after subtracting 1314 from 1410.
Take the next digit (0) from the dividend and append it to 96, then repeat: 960 / 438

Step 6:
If we divide 960 by 438, we get 2 and a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 2232.0
If we take 876 away from 960, we end up with 84.
Fetch the next digit (6) from the dividend, attach it to 84 and continue: 846 / 438

Let's proceed to step 7:
438 can be fit into 846 1 times, resulting in a remainder of 408.
Write down 1 as next digit of the result. 
Result so far: 22321.0
If we subtract 438 from 846, we get 408.
Append the next digit (5) from the dividend to 408 and continue with: 4085 / 438

Going ahead to step 8:
438 can be fit into 4085 9 times, resulting in a remainder of 143.
The next digit of our result is 9. 
Result so far: 223219.0
If we subtract 3942 from 4085, we get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 9:
1430 divided by 438 is 3 with a remainder of 116.
Put 3 as the next digit of the answer. 
Result so far: 223219.3
If we subtract 1314 from 1430, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 10:
If we divide 1160 by 438, we get 2 and a remainder of 284.
Use 2 as the next digit of our solution. 
Result so far: 223219.32
The remainder is 284 after subtracting 876 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 11:
The number 438 fits into 2840 6 times, leaving a remainder of 212.
The next digit of our result is 6. 
Result so far: 223219.326
If we subtract 2628 from 2840, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 12:
438 goes into 2120 4 times with a remainder of 368.
Put 4 as the next digit of the answer. 
Result so far: 223219.3264
If we subtract 1752 from 2120, 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.

On to step 13:
The number 438 fits into 3680 8 times, leaving a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 223219.32648
Deduct 3504 from 3680 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 14:
If we divide 1760 by 438, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 223219.326484
Deduct 1752 from 1760 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 15:
438 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 223219.326484
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 16:
The number 438 fits into 800 1 times, leaving a remainder of 362.
The next digit of our result is 1. 
Result so far: 223219.32648401
Subtract 438 from 800 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

The quotient of the division is 223219.32648401, and the remainder is 3.62e-07.
