77010746 ÷ 643 
Our goal is to divide 77010746 by 643.

Let's proceed to step 1:
643 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 643

Moving on to step 2:
When dividing 77 by 643, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Take the next digit (0) from the dividend and append it to 77, then repeat: 770 / 643

Going ahead to step 3:
The number 643 fits into 770 1 times, leaving a remainder of 127.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 643 from 770, we get 127.
Fetch the next digit (1) from the dividend, attach it to 127 and continue: 1271 / 643

Let's proceed to step 4:
The number 643 fits into 1271 1 times, leaving a remainder of 628.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 643 from 1271 to get 628.
Bring next digit (0) of the dividend behind the 628 and repeat the process: 6280 / 643

Moving on to step 5:
643 can be fit into 6280 9 times, resulting in a remainder of 493.
Use 9 as the next digit of our solution. 
Result so far: 119.0
Subtracting 5787 from 6280 leaves us with 493.
Grab the next digit (7) from the dividend, add it to 493, then carry on: 4937 / 643

Going ahead to step 6:
When dividing 4937 by 643, we get 7 with a remainder of 436.
Use 7 as the next digit of our solution. 
Result so far: 1197.0
If we subtract 4501 from 4937, we get 436.
Include the next digit (4) from the dividend after 436, then repeat: 4364 / 643

Advancing to step 7:
4364 divided by 643 is 6 with a remainder of 506.
Write down 6 as next digit of the result. 
Result so far: 11976.0
Deduct 3858 from 4364 and we're left with 506.
Append the next digit (6) from the dividend to 506 and continue with: 5066 / 643

Let's proceed to step 8:
If we divide 5066 by 643, we get 7 and a remainder of 565.
Put 7 as the next digit of the answer. 
Result so far: 119767.0
Subtracting 4501 from 5066 leaves us with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Going ahead to step 9:
If we divide 5650 by 643, we get 8 and a remainder of 506.
Record the quotient 8 as the next digit in the result. 
Result so far: 119767.8
The remainder is 506 after subtracting 5144 from 5650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Let's proceed to step 10:
643 goes into 5060 7 times with a remainder of 559.
Use 7 as the next digit of our solution. 
Result so far: 119767.87
Subtract 4501 from 5060 to get 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Moving on to step 11:
The number 643 fits into 5590 8 times, leaving a remainder of 446.
The number 8 becomes the next digit in our result. 
Result so far: 119767.878
Subtract 5144 from 5590 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 12:
The number 643 fits into 4460 6 times, leaving a remainder of 602.
Write down 6 as next digit of the result. 
Result so far: 119767.8786
Deduct 3858 from 4460 and we're left with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Advancing to step 13:
The number 643 fits into 6020 9 times, leaving a remainder of 233.
Record the quotient 9 as the next digit in the result. 
Result so far: 119767.87869
Deduct 5787 from 6020 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 14:
643 can be fit into 2330 3 times, resulting in a remainder of 401.
Put 3 as the next digit of the answer. 
Result so far: 119767.878693
Subtract 1929 from 2330 to get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Let's proceed to step 15:
643 can be fit into 4010 6 times, resulting in a remainder of 152.
Record the quotient 6 as the next digit in the result. 
Result so far: 119767.8786936
The remainder is 152 after subtracting 3858 from 4010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 16:
1520 divided by 643 is 2 with a remainder of 234.
Record the quotient 2 as the next digit in the result. 
Result so far: 119767.87869362
The remainder is 234 after subtracting 1286 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

After the division, we end up with 119767.87869362 and a remainder of 2.34e-07.
