90700421 divided by 186 
Our goal is to divide 90700421 by 186.

Moving on to step 1:
When dividing 9 by 186, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 186

On to step 2:
186 can be fit into 90 0 times, resulting in a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Append the next digit (7) from the dividend to 90 and continue with: 907 / 186

Let's proceed to step 3:
907 divided by 186 is 4 with a remainder of 163.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 163 after subtracting 744 from 907.
Include the next digit (0) from the dividend after 163, then repeat: 1630 / 186

Let's proceed to step 4:
When dividing 1630 by 186, we get 8 with a remainder of 142.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we subtract 1488 from 1630, we get 142.
Fetch the next digit (0) from the dividend, attach it to 142 and continue: 1420 / 186

Advancing to step 5:
The number 186 fits into 1420 7 times, leaving a remainder of 118.
Write down 7 as next digit of the result. 
Result so far: 487.0
If we subtract 1302 from 1420, we get 118.
Bring next digit (4) of the dividend behind the 118 and repeat the process: 1184 / 186

On to step 6:
If we divide 1184 by 186, we get 6 and a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 4876.0
If we subtract 1116 from 1184, we get 68.
Take the next digit (2) from the dividend and append it to 68, then repeat: 682 / 186

Going ahead to step 7:
186 can be fit into 682 3 times, resulting in a remainder of 124.
Put 3 as the next digit of the answer. 
Result so far: 48763.0
If we subtract 558 from 682, we get 124.
Append the next digit (1) from the dividend to 124 and continue with: 1241 / 186

Advancing to step 8:
When dividing 1241 by 186, we get 6 with a remainder of 125.
The next digit of our result is 6. 
Result so far: 487636.0
Subtract 1116 from 1241 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 9:
When dividing 1250 by 186, we get 6 with a remainder of 134.
The number 6 becomes the next digit in our result. 
Result so far: 487636.6
Subtract 1116 from 1250 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.

Let's proceed to step 10:
186 goes into 1340 7 times with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 487636.67
Subtract 1302 from 1340 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
380 divided by 186 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 487636.672
If we subtract 372 from 380, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
When dividing 80 by 186, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 487636.672
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
186 goes into 800 4 times with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 487636.67204
Deduct 744 from 800 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
The number 186 fits into 560 3 times, leaving a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 487636.672043
Deduct 558 from 560 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 15:
When dividing 20 by 186, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 487636.672043
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 16:
When dividing 200 by 186, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 487636.67204301
If we subtract 186 from 200, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 487636.67204301, and the remainder is 1.4e-08.
