We divide 76976919 by 646
Our goal is to divide 76976919 by 646.

On to step 1:
The number 646 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 646

Step 2:
If we divide 76 by 646, we get 0 and a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 646

Going ahead to step 3:
If we divide 769 by 646, we get 1 and a remainder of 123.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 646 from 769 leaves us with 123.
Bring next digit (7) of the dividend behind the 123 and repeat the process: 1237 / 646

On to step 4:
646 goes into 1237 1 times with a remainder of 591.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 591 after subtracting 646 from 1237.
Fetch the next digit (6) from the dividend, attach it to 591 and continue: 5916 / 646

On to step 5:
646 can be fit into 5916 9 times, resulting in a remainder of 102.
The next digit of our result is 9. 
Result so far: 119.0
If we subtract 5814 from 5916, we get 102.
Include the next digit (9) from the dividend after 102, then repeat: 1029 / 646

Moving on to step 6:
If we divide 1029 by 646, we get 1 and a remainder of 383.
Put 1 as the next digit of the answer. 
Result so far: 1191.0
Deduct 646 from 1029 and we're left with 383.
Fetch the next digit (1) from the dividend, attach it to 383 and continue: 3831 / 646

On to step 7:
646 goes into 3831 5 times with a remainder of 601.
Record the quotient 5 as the next digit in the result. 
Result so far: 11915.0
If we subtract 3230 from 3831, we get 601.
Grab the next digit (9) from the dividend, add it to 601, then carry on: 6019 / 646

Advancing to step 8:
The number 646 fits into 6019 9 times, leaving a remainder of 205.
Put 9 as the next digit of the answer. 
Result so far: 119159.0
If we take 5814 away from 6019, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 9:
646 can be fit into 2050 3 times, resulting in a remainder of 112.
The number 3 becomes the next digit in our result. 
Result so far: 119159.3
If we subtract 1938 from 2050, we get 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 10:
If we divide 1120 by 646, we get 1 and a remainder of 474.
Write down 1 as next digit of the result. 
Result so far: 119159.31
If we take 646 away from 1120, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 11:
646 goes into 4740 7 times with a remainder of 218.
Write down 7 as next digit of the result. 
Result so far: 119159.317
If we subtract 4522 from 4740, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 12:
If we divide 2180 by 646, we get 3 and a remainder of 242.
Write down 3 as next digit of the result. 
Result so far: 119159.3173
Subtract 1938 from 2180 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 13:
646 can be fit into 2420 3 times, resulting in a remainder of 482.
The number 3 becomes the next digit in our result. 
Result so far: 119159.31733
If we subtract 1938 from 2420, we get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

After the division, we end up with 119159.31733 and a remainder of 0.000482.
