37551385 divided by 420 
We want to divide 37551385 by 420.

On to step 1:
420 can be fit into 3 0 times, resulting in 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.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 420

On to step 2:
If we divide 37 by 420, we get 0 and a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 420

Let's proceed to step 3:
420 goes into 375 0 times with a remainder of 375.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 375 after subtracting 0 from 375.
Include the next digit (5) from the dividend after 375, then repeat: 3755 / 420

Let's proceed to step 4:
When dividing 3755 by 420, we get 8 with a remainder of 395.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 3360 away from 3755, we end up with 395.
Take the next digit (1) from the dividend and append it to 395, then repeat: 3951 / 420

On to step 5:
420 can be fit into 3951 9 times, resulting in a remainder of 171.
The next digit of our result is 9. 
Result so far: 89.0
The remainder is 171 after subtracting 3780 from 3951.
Fetch the next digit (3) from the dividend, attach it to 171 and continue: 1713 / 420

Step 6:
420 goes into 1713 4 times with a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 894.0
The remainder is 33 after subtracting 1680 from 1713.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 420

Advancing to step 7:
The number 420 fits into 338 0 times, leaving a remainder of 338.
The next digit of our result is 0. 
Result so far: 8940.0
The remainder is 338 after subtracting 0 from 338.
Fetch the next digit (5) from the dividend, attach it to 338 and continue: 3385 / 420

Going ahead to step 8:
420 goes into 3385 8 times with a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 89408.0
If we take 3360 away from 3385, we end up 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.

Going ahead to step 9:
The number 420 fits into 250 0 times, leaving a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 89408.0
If we take 0 away from 250, we end up 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:
420 can be fit into 2500 5 times, resulting in a remainder of 400.
The next digit of our result is 5. 
Result so far: 89408.05
Subtracting 2100 from 2500 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 11:
When dividing 4000 by 420, we get 9 with a remainder of 220.
Write down 9 as next digit of the result. 
Result so far: 89408.059
Subtract 3780 from 4000 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 12:
420 can be fit into 2200 5 times, resulting in a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 89408.0595
Deduct 2100 from 2200 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 13:
When dividing 1000 by 420, we get 2 with a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 89408.05952
The remainder is 160 after subtracting 840 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
420 goes into 1600 3 times with a remainder of 340.
Record the quotient 3 as the next digit in the result. 
Result so far: 89408.059523
Subtract 1260 from 1600 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 15:
When dividing 3400 by 420, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 89408.0595238
If we subtract 3360 from 3400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 16:
400 divided by 420 is 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 89408.0595238
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 89408.0595238 and a remainder of 4e-07.
