76854428 divided by 642 
We want to divide 76854428 by 642.

Step 1:
7 divided by 642 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 642

Going ahead to step 2:
When dividing 76 by 642, we get 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Include the next digit (8) from the dividend after 76, then repeat: 768 / 642

Step 3:
642 can be fit into 768 1 times, resulting in a remainder of 126.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 642 from 768, we get 126.
Take the next digit (5) from the dividend and append it to 126, then repeat: 1265 / 642

Let's proceed to step 4:
1265 divided by 642 is 1 with a remainder of 623.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 623 after subtracting 642 from 1265.
Fetch the next digit (4) from the dividend, attach it to 623 and continue: 6234 / 642

Let's proceed to step 5:
642 can be fit into 6234 9 times, resulting in a remainder of 456.
The next digit of our result is 9. 
Result so far: 119.0
If we subtract 5778 from 6234, we get 456.
Bring next digit (4) of the dividend behind the 456 and repeat the process: 4564 / 642

Going ahead to step 6:
If we divide 4564 by 642, we get 7 and a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 1197.0
Deduct 4494 from 4564 and we're left with 70.
Bring next digit (2) of the dividend behind the 70 and repeat the process: 702 / 642

Going ahead to step 7:
The number 642 fits into 702 1 times, leaving a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 11971.0
If we subtract 642 from 702, we get 60.
Bring next digit (8) of the dividend behind the 60 and repeat the process: 608 / 642

Moving on to step 8:
The number 642 fits into 608 0 times, leaving a remainder of 608.
Put 0 as the next digit of the answer. 
Result so far: 119710.0
Deduct 0 from 608 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 9:
When dividing 6080 by 642, we get 9 with a remainder of 302.
Record the quotient 9 as the next digit in the result. 
Result so far: 119710.9
If we subtract 5778 from 6080, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 10:
3020 divided by 642 is 4 with a remainder of 452.
Record the quotient 4 as the next digit in the result. 
Result so far: 119710.94
Subtracting 2568 from 3020 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Step 11:
642 can be fit into 4520 7 times, resulting in a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 119710.947
Subtracting 4494 from 4520 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
If we divide 260 by 642, we get 0 and a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 119710.947
The remainder is 260 after subtracting 0 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 13:
The number 642 fits into 2600 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 119710.94704
Subtracting 2568 from 2600 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
When dividing 320 by 642, we get 0 with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 119710.94704
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 15:
When dividing 3200 by 642, we get 4 with a remainder of 632.
The number 4 becomes the next digit in our result. 
Result so far: 119710.9470404
Subtract 2568 from 3200 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Moving on to step 16:
If we divide 6320 by 642, we get 9 and a remainder of 542.
Use 9 as the next digit of our solution. 
Result so far: 119710.94704049
If we take 5778 away from 6320, we end up with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

After the division, we end up with 119710.94704049 and a remainder of 5.42e-07.
