We're dividing 76667776 by 551 
Our goal is to divide 76667776 by 551.

Let's proceed to step 1:
The number 551 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 551

Going ahead to step 2:
When dividing 76 by 551, we get 0 with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Append the next digit (6) from the dividend to 76 and continue with: 766 / 551

On to step 3:
551 goes into 766 1 times with a remainder of 215.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 551 from 766 to get 215.
Append the next digit (6) from the dividend to 215 and continue with: 2156 / 551

Going ahead to step 4:
When dividing 2156 by 551, we get 3 with a remainder of 503.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1653 from 2156 to get 503.
Fetch the next digit (7) from the dividend, attach it to 503 and continue: 5037 / 551

Let's proceed to step 5:
551 goes into 5037 9 times with a remainder of 78.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
If we take 4959 away from 5037, we end up with 78.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 551

On to step 6:
551 goes into 787 1 times with a remainder of 236.
Use 1 as the next digit of our solution. 
Result so far: 1391.0
If we take 551 away from 787, we end up with 236.
Include the next digit (7) from the dividend after 236, then repeat: 2367 / 551

Step 7:
551 goes into 2367 4 times with a remainder of 163.
Use 4 as the next digit of our solution. 
Result so far: 13914.0
If we subtract 2204 from 2367, we get 163.
Bring next digit (6) of the dividend behind the 163 and repeat the process: 1636 / 551

Advancing to step 8:
551 goes into 1636 2 times with a remainder of 534.
Record the quotient 2 as the next digit in the result. 
Result so far: 139142.0
Subtract 1102 from 1636 to get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Advancing to step 9:
551 can be fit into 5340 9 times, resulting in a remainder of 381.
The next digit of our result is 9. 
Result so far: 139142.9
Subtract 4959 from 5340 to get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 10:
The number 551 fits into 3810 6 times, leaving a remainder of 504.
Record the quotient 6 as the next digit in the result. 
Result so far: 139142.96
Deduct 3306 from 3810 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 11:
551 goes into 5040 9 times with a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 139142.969
The remainder is 81 after subtracting 4959 from 5040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 12:
551 goes into 810 1 times with a remainder of 259.
The next digit of our result is 1. 
Result so far: 139142.9691
Subtract 551 from 810 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 13:
When dividing 2590 by 551, we get 4 with a remainder of 386.
The next digit of our result is 4. 
Result so far: 139142.96914
Subtracting 2204 from 2590 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 14:
If we divide 3860 by 551, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 139142.969147
The remainder is 3 after subtracting 3857 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 15:
30 divided by 551 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 139142.969147
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 16:
551 goes into 300 0 times with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 139142.969147
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 139142.969147, with a leftover of 3e-07.
