We divide 10641668 by 138
We want to divide 10641668 by 138.

Advancing to step 1:
When dividing 1 by 138, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 138

Going ahead to step 2:
138 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 138

Moving on to step 3:
138 can be fit into 106 0 times, resulting in a remainder of 106.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 106 after subtracting 0 from 106.
Append the next digit (4) from the dividend to 106 and continue with: 1064 / 138

On to step 4:
The number 138 fits into 1064 7 times, leaving a remainder of 98.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 966 from 1064 to get 98.
Bring next digit (1) of the dividend behind the 98 and repeat the process: 981 / 138

Step 5:
If we divide 981 by 138, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 77.0
Subtracting 966 from 981 leaves us with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 138

Let's proceed to step 6:
If we divide 156 by 138, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 771.0
If we take 138 away from 156, we end up with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 138

On to step 7:
When dividing 186 by 138, we get 1 with a remainder of 48.
The next digit of our result is 1. 
Result so far: 7711.0
Deduct 138 from 186 and we're left with 48.
Grab the next digit (8) from the dividend, add it to 48, then carry on: 488 / 138

Advancing to step 8:
If we divide 488 by 138, we get 3 and a remainder of 74.
Write down 3 as next digit of the result. 
Result so far: 77113.0
The remainder is 74 after subtracting 414 from 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 9:
The number 138 fits into 740 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 77113.5
If we take 690 away from 740, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
If we divide 500 by 138, we get 3 and a remainder of 86.
The next digit of our result is 3. 
Result so far: 77113.53
Subtracting 414 from 500 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 11:
138 can be fit into 860 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 77113.536
Deduct 828 from 860 and we're left 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.

Step 12:
If we divide 320 by 138, we get 2 and a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 77113.5362
The remainder is 44 after subtracting 276 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 13:
If we divide 440 by 138, we get 3 and a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 77113.53623
If we take 414 away from 440, we end up 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 14:
When dividing 260 by 138, we get 1 with a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 77113.536231
Subtracting 138 from 260 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 15:
When dividing 1220 by 138, we get 8 with a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 77113.5362318
The remainder is 116 after subtracting 1104 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 16:
138 can be fit into 1160 8 times, resulting in a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 77113.53623188
Subtract 1104 from 1160 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 77113.53623188, with a leftover of 5.6e-08.
