Let's divide 97431943 by 77
We want to divide 97431943 by 77.

Step 1:
When dividing 9 by 77, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 77

On to step 2:
77 can be fit into 97 1 times, resulting in a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 77 from 97 to get 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 77

Advancing to step 3:
77 can be fit into 204 2 times, resulting in a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 154 from 204 and we're left with 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 77

Step 4:
If we divide 503 by 77, we get 6 and a remainder of 41.
Put 6 as the next digit of the answer. 
Result so far: 126.0
If we subtract 462 from 503, we get 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 77

Going ahead to step 5:
If we divide 411 by 77, we get 5 and a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 1265.0
Subtract 385 from 411 to get 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 77

Advancing to step 6:
269 divided by 77 is 3 with a remainder of 38.
The next digit of our result is 3. 
Result so far: 12653.0
Subtract 231 from 269 to get 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 77

Going ahead to step 7:
77 goes into 384 4 times with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 126534.0
The remainder is 76 after subtracting 308 from 384.
Bring next digit (3) of the dividend behind the 76 and repeat the process: 763 / 77

Let's proceed to step 8:
763 divided by 77 is 9 with a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 1265349.0
The remainder is 70 after subtracting 693 from 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
77 goes into 700 9 times with a remainder of 7.
The next digit of our result is 9. 
Result so far: 1265349.9
Subtracting 693 from 700 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
70 divided by 77 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 1265349.9
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
77 can be fit into 700 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 1265349.909
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
77 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 1265349.909
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 13:
The number 77 fits into 700 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 1265349.90909
Subtract 693 from 700 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
77 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 1265349.90909
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 15:
77 goes into 700 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 1265349.9090909
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 16:
77 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 1265349.9090909
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 1265349.9090909 with a remaining 7e-08.
