77674551 divided by 138 
We want to divide 77674551 by 138.

Advancing to step 1:
The number 138 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 138

Step 2:
If we divide 77 by 138, we get 0 and a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Take the next digit (6) from the dividend and append it to 77, then repeat: 776 / 138

Let's proceed to step 3:
138 goes into 776 5 times with a remainder of 86.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 690 from 776 leaves us with 86.
Grab the next digit (7) from the dividend, add it to 86, then carry on: 867 / 138

Moving on to step 4:
867 divided by 138 is 6 with a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtracting 828 from 867 leaves us with 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 138

Let's proceed to step 5:
When dividing 394 by 138, we get 2 with a remainder of 118.
Put 2 as the next digit of the answer. 
Result so far: 562.0
Subtracting 276 from 394 leaves us with 118.
Append the next digit (5) from the dividend to 118 and continue with: 1185 / 138

Going ahead to step 6:
138 can be fit into 1185 8 times, resulting in a remainder of 81.
Put 8 as the next digit of the answer. 
Result so far: 5628.0
Deduct 1104 from 1185 and we're left with 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 138

Let's proceed to step 7:
138 goes into 815 5 times with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 56285.0
If we take 690 away from 815, we end up with 125.
Append the next digit (1) from the dividend to 125 and continue with: 1251 / 138

Step 8:
When dividing 1251 by 138, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 562859.0
If we subtract 1242 from 1251, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
90 divided by 138 is 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 562859.0
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
138 goes into 900 6 times with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 562859.06
Deduct 828 from 900 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
138 goes into 720 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 562859.065
If we take 690 away from 720, we end up 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.

On to step 12:
138 can be fit into 300 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 562859.0652
If we take 276 away from 300, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
If we divide 240 by 138, we get 1 and a remainder of 102.
Write down 1 as next digit of the result. 
Result so far: 562859.06521
If we subtract 138 from 240, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 14:
1020 divided by 138 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 562859.065217
Subtracting 966 from 1020 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 15:
The number 138 fits into 540 3 times, leaving a remainder of 126.
Write down 3 as next digit of the result. 
Result so far: 562859.0652173
If we take 414 away from 540, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 16:
The number 138 fits into 1260 9 times, leaving a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 562859.06521739
Deduct 1242 from 1260 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 562859.06521739, with a leftover of 1.8e-08.
