126187 ÷ 37 
We're looking to find how many times 37 goes into 126187.

Going ahead to step 1:
37 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 37

Step 2:
37 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 37

Advancing to step 3:
126 divided by 37 is 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 15 after subtracting 111 from 126.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 37

Let's proceed to step 4:
If we divide 151 by 37, we get 4 and a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 148 from 151 to get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 37

Going ahead to step 5:
When dividing 38 by 37, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 341.0
The remainder is 1 after subtracting 37 from 38.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 37

On to step 6:
37 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 3410.0
Subtract 0 from 17 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
37 can be fit into 170 4 times, resulting in a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 3410.4
Subtracting 148 from 170 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
The number 37 fits into 220 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 3410.45
Subtracting 185 from 220 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
37 goes into 350 9 times with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 3410.459
Deduct 333 from 350 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
If we divide 170 by 37, we get 4 and a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 3410.4594
Subtract 148 from 170 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
When dividing 220 by 37, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 3410.45945
If we take 185 away from 220, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 12:
37 goes into 350 9 times with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 3410.459459
Deduct 333 from 350 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
37 can be fit into 170 4 times, resulting in a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 3410.4594594
The remainder is 22 after subtracting 148 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
37 can be fit into 220 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 3410.45945945
Subtracting 185 from 220 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 3410.45945945, with a leftover of 3.5e-08.
