37421215 divided by 810 
We want to figure out the number of times 37421215 can be divided by 810.

Let's proceed to step 1:
When dividing 3 by 810, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 810

Let's proceed to step 2:
810 can be fit into 37 0 times, resulting in a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 810

Advancing to step 3:
374 divided by 810 is 0 with a remainder of 374.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 374, we end up with 374.
Fetch the next digit (2) from the dividend, attach it to 374 and continue: 3742 / 810

On to step 4:
810 can be fit into 3742 4 times, resulting in a remainder of 502.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 3240 from 3742 leaves us with 502.
Fetch the next digit (1) from the dividend, attach it to 502 and continue: 5021 / 810

Let's proceed to step 5:
If we divide 5021 by 810, we get 6 and a remainder of 161.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtracting 4860 from 5021 leaves us with 161.
Fetch the next digit (2) from the dividend, attach it to 161 and continue: 1612 / 810

Let's proceed to step 6:
If we divide 1612 by 810, we get 1 and a remainder of 802.
Write down 1 as next digit of the result. 
Result so far: 461.0
The remainder is 802 after subtracting 810 from 1612.
Grab the next digit (1) from the dividend, add it to 802, then carry on: 8021 / 810

Moving on to step 7:
When dividing 8021 by 810, we get 9 with a remainder of 731.
The number 9 becomes the next digit in our result. 
Result so far: 4619.0
If we subtract 7290 from 8021, we get 731.
Take the next digit (5) from the dividend and append it to 731, then repeat: 7315 / 810

On to step 8:
If we divide 7315 by 810, we get 9 and a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 46199.0
Deduct 7290 from 7315 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
If we divide 250 by 810, we get 0 and a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 46199.0
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 10:
810 goes into 2500 3 times with a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 46199.03
If we subtract 2430 from 2500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
If we divide 700 by 810, we get 0 and a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 46199.03
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 12:
810 can be fit into 7000 8 times, resulting in a remainder of 520.
Use 8 as the next digit of our solution. 
Result so far: 46199.0308
Deduct 6480 from 7000 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 13:
If we divide 5200 by 810, we get 6 and a remainder of 340.
Record the quotient 6 as the next digit in the result. 
Result so far: 46199.03086
If we take 4860 away from 5200, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 14:
The number 810 fits into 3400 4 times, leaving a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 46199.030864
If we take 3240 away from 3400, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 15:
810 can be fit into 1600 1 times, resulting in a remainder of 790.
Record the quotient 1 as the next digit in the result. 
Result so far: 46199.0308641
The remainder is 790 after subtracting 810 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

On to step 16:
If we divide 7900 by 810, we get 9 and a remainder of 610.
Record the quotient 9 as the next digit in the result. 
Result so far: 46199.03086419
Deduct 7290 from 7900 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

The quotient of the division is 46199.03086419, and the remainder is 6.1e-07.
