76861690 ÷ 138 
Let's see how many times 138 fits into 76861690.

Step 1:
The number 138 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 138

On to step 2:
The number 138 fits into 76 0 times, leaving a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Grab the next digit (8) from the dividend, add it to 76, then carry on: 768 / 138

Let's proceed to step 3:
138 can be fit into 768 5 times, resulting in a remainder of 78.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 690 from 768 and we're left with 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 138

Let's proceed to step 4:
If we divide 786 by 138, we get 5 and a remainder of 96.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
If we subtract 690 from 786, we get 96.
Fetch the next digit (1) from the dividend, attach it to 96 and continue: 961 / 138

On to step 5:
138 goes into 961 6 times with a remainder of 133.
The next digit of our result is 6. 
Result so far: 556.0
Deduct 828 from 961 and we're left with 133.
Take the next digit (6) from the dividend and append it to 133, then repeat: 1336 / 138

Moving on to step 6:
If we divide 1336 by 138, we get 9 and a remainder of 94.
Write down 9 as next digit of the result. 
Result so far: 5569.0
Subtracting 1242 from 1336 leaves us with 94.
Bring next digit (9) of the dividend behind the 94 and repeat the process: 949 / 138

Step 7:
949 divided by 138 is 6 with a remainder of 121.
Use 6 as the next digit of our solution. 
Result so far: 55696.0
Subtracting 828 from 949 leaves us with 121.
Include the next digit (0) from the dividend after 121, then repeat: 1210 / 138

On to step 8:
When dividing 1210 by 138, we get 8 with a remainder of 106.
The next digit of our result is 8. 
Result so far: 556968.0
If we take 1104 away from 1210, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 9:
The number 138 fits into 1060 7 times, leaving a remainder of 94.
Record the quotient 7 as the next digit in the result. 
Result so far: 556968.7
Subtract 966 from 1060 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 10:
138 goes into 940 6 times with a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 556968.76
If we subtract 828 from 940, 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.

Let's proceed to step 11:
1120 divided by 138 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 556968.768
Subtracting 1104 from 1120 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
The number 138 fits into 160 1 times, leaving a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 556968.7681
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
138 can be fit into 220 1 times, resulting in a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 556968.76811
If we subtract 138 from 220, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Our division results in 556968.76811 with a remaining 8.2e-05.
