We're dividing 13646290 by 149 
Let's see how many times 149 fits into 13646290.

Advancing to step 1:
When dividing 1 by 149, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 149

On to step 2:
When dividing 13 by 149, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 149

Step 3:
149 can be fit into 136 0 times, resulting in a remainder of 136.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 136, we get 136.
Grab the next digit (4) from the dividend, add it to 136, then carry on: 1364 / 149

Advancing to step 4:
If we divide 1364 by 149, we get 9 and a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 1341 from 1364 leaves us with 23.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 149

Moving on to step 5:
The number 149 fits into 236 1 times, leaving a remainder of 87.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Subtracting 149 from 236 leaves us with 87.
Take the next digit (2) from the dividend and append it to 87, then repeat: 872 / 149

Advancing to step 6:
149 can be fit into 872 5 times, resulting in a remainder of 127.
Put 5 as the next digit of the answer. 
Result so far: 915.0
Deduct 745 from 872 and we're left with 127.
Fetch the next digit (9) from the dividend, attach it to 127 and continue: 1279 / 149

On to step 7:
When dividing 1279 by 149, we get 8 with a remainder of 87.
Record the quotient 8 as the next digit in the result. 
Result so far: 9158.0
If we take 1192 away from 1279, we end up with 87.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 149

Step 8:
The number 149 fits into 870 5 times, leaving a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 91585.0
Deduct 745 from 870 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 9:
The number 149 fits into 1250 8 times, leaving a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 91585.8
If we take 1192 away from 1250, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
149 can be fit into 580 3 times, resulting in a remainder of 133.
Record the quotient 3 as the next digit in the result. 
Result so far: 91585.83
Subtract 447 from 580 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 11:
149 can be fit into 1330 8 times, resulting in a remainder of 138.
Put 8 as the next digit of the answer. 
Result so far: 91585.838
If we take 1192 away from 1330, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 12:
When dividing 1380 by 149, we get 9 with a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 91585.8389
Subtracting 1341 from 1380 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 13:
149 goes into 390 2 times with a remainder of 92.
The next digit of our result is 2. 
Result so far: 91585.83892
The remainder is 92 after subtracting 298 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 14:
If we divide 920 by 149, we get 6 and a remainder of 26.
The next digit of our result is 6. 
Result so far: 91585.838926
Subtracting 894 from 920 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 15:
If we divide 260 by 149, we get 1 and a remainder of 111.
Use 1 as the next digit of our solution. 
Result so far: 91585.8389261
If we subtract 149 from 260, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 16:
149 goes into 1110 7 times with a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 91585.83892617
Deduct 1043 from 1110 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The final result is 91585.83892617 with a remainder of 6.7e-08.
