We're dividing 139321 by 37 
Our goal is to divide 139321 by 37.

Advancing to step 1:
1 divided by 37 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 37

Step 2:
The number 37 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 37

Let's proceed to step 3:
If we divide 139 by 37, we get 3 and a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 111 from 139 to get 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 37

Advancing to step 4:
If we divide 283 by 37, we get 7 and a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Deduct 259 from 283 and we're left with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 37

Advancing to step 5:
When dividing 242 by 37, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 376.0
The remainder is 20 after subtracting 222 from 242.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 37

Going ahead to step 6:
201 divided by 37 is 5 with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 3765.0
If we subtract 185 from 201, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
37 goes into 160 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 3765.4
If we subtract 148 from 160, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
When dividing 120 by 37, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3765.43
Deduct 111 from 120 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
90 divided by 37 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 3765.432
If we subtract 74 from 90, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
If we divide 160 by 37, we get 4 and a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 3765.4324
The remainder is 12 after subtracting 148 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
120 divided by 37 is 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3765.43243
If we take 111 away from 120, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
90 divided by 37 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 3765.432432
Deduct 74 from 90 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
If we divide 160 by 37, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 3765.4324324
If we take 148 away from 160, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
37 can be fit into 120 3 times, resulting in a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3765.43243243
Subtracting 111 from 120 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 3765.43243243 and a remainder of 9e-09.
