13107161 ÷ 149 
We want to figure out the number of times 13107161 can be divided by 149.

Moving on 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
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 149

Let's proceed to step 2:
When dividing 13 by 149, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 149

Moving on to step 3:
149 goes into 131 0 times with a remainder of 131.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 131, we get 131.
Include the next digit (0) from the dividend after 131, then repeat: 1310 / 149

Going ahead to step 4:
When dividing 1310 by 149, we get 8 with a remainder of 118.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 118 after subtracting 1192 from 1310.
Bring next digit (7) of the dividend behind the 118 and repeat the process: 1187 / 149

On to step 5:
If we divide 1187 by 149, we get 7 and a remainder of 144.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
The remainder is 144 after subtracting 1043 from 1187.
Append the next digit (1) from the dividend to 144 and continue with: 1441 / 149

Let's proceed to step 6:
1441 divided by 149 is 9 with a remainder of 100.
Record the quotient 9 as the next digit in the result. 
Result so far: 879.0
Subtract 1341 from 1441 to get 100.
Take the next digit (6) from the dividend and append it to 100, then repeat: 1006 / 149

Step 7:
The number 149 fits into 1006 6 times, leaving a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 8796.0
The remainder is 112 after subtracting 894 from 1006.
Take the next digit (1) from the dividend and append it to 112, then repeat: 1121 / 149

Let's proceed to step 8:
149 goes into 1121 7 times with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 87967.0
Deduct 1043 from 1121 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 9:
When dividing 780 by 149, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 87967.5
Subtract 745 from 780 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
149 can be fit into 350 2 times, resulting in a remainder of 52.
The next digit of our result is 2. 
Result so far: 87967.52
Subtract 298 from 350 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
The number 149 fits into 520 3 times, leaving a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 87967.523
Subtract 447 from 520 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 12:
If we divide 730 by 149, we get 4 and a remainder of 134.
The next digit of our result is 4. 
Result so far: 87967.5234
Subtract 596 from 730 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 13:
The number 149 fits into 1340 8 times, leaving a remainder of 148.
The next digit of our result is 8. 
Result so far: 87967.52348
Subtracting 1192 from 1340 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 14:
If we divide 1480 by 149, we get 9 and a remainder of 139.
Put 9 as the next digit of the answer. 
Result so far: 87967.523489
Subtracting 1341 from 1480 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 15:
149 goes into 1390 9 times with a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 87967.5234899
Deduct 1341 from 1390 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Our division results in 87967.5234899 with a remaining 4.9e-07.
