158686 ÷ 37 
We want to figure out the number of times 158686 can be divided by 37.

Moving on to step 1:
The number 37 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 37

On to step 2:
37 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 37

Moving on to step 3:
37 goes into 158 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 148 from 158 to get 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 37

Let's proceed to step 4:
106 divided by 37 is 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 42.0
Deduct 74 from 106 and we're left with 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 37

Moving on to step 5:
37 goes into 328 8 times with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 428.0
Subtracting 296 from 328 leaves us with 32.
Take the next digit (6) from the dividend and append it to 32, then repeat: 326 / 37

Let's proceed to step 6:
The number 37 fits into 326 8 times, leaving a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 4288.0
Subtracting 296 from 326 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
The number 37 fits into 300 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 4288.8
Subtract 296 from 300 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
37 can be fit into 40 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 4288.81
Subtract 37 from 40 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
When dividing 30 by 37, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 4288.81
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
When dividing 300 by 37, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 4288.8108
If we subtract 296 from 300, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
40 divided by 37 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 4288.81081
Subtract 37 from 40 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
37 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 4288.81081
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
37 goes into 300 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 4288.8108108
Subtracting 296 from 300 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
40 divided by 37 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 4288.81081081
The remainder is 3 after subtracting 37 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 4288.81081081, with a leftover of 3e-09.
