We're dividing 91337129 by 420 
Let's see how many times 420 fits into 91337129.

Advancing to step 1:
9 divided by 420 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 420

On to step 2:
When dividing 91 by 420, we get 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Bring next digit (3) of the dividend behind the 91 and repeat the process: 913 / 420

Let's proceed to step 3:
420 goes into 913 2 times with a remainder of 73.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 840 from 913 leaves us with 73.
Take the next digit (3) from the dividend and append it to 73, then repeat: 733 / 420

Advancing to step 4:
When dividing 733 by 420, we get 1 with a remainder of 313.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 420 from 733 and we're left with 313.
Append the next digit (7) from the dividend to 313 and continue with: 3137 / 420

Moving on to step 5:
When dividing 3137 by 420, we get 7 with a remainder of 197.
The next digit of our result is 7. 
Result so far: 217.0
Subtracting 2940 from 3137 leaves us with 197.
Bring next digit (1) of the dividend behind the 197 and repeat the process: 1971 / 420

Let's proceed to step 6:
420 goes into 1971 4 times with a remainder of 291.
Put 4 as the next digit of the answer. 
Result so far: 2174.0
Subtract 1680 from 1971 to get 291.
Take the next digit (2) from the dividend and append it to 291, then repeat: 2912 / 420

Going ahead to step 7:
If we divide 2912 by 420, we get 6 and a remainder of 392.
Write down 6 as next digit of the result. 
Result so far: 21746.0
If we take 2520 away from 2912, we end up with 392.
Grab the next digit (9) from the dividend, add it to 392, then carry on: 3929 / 420

Going ahead to step 8:
When dividing 3929 by 420, we get 9 with a remainder of 149.
Use 9 as the next digit of our solution. 
Result so far: 217469.0
Subtracting 3780 from 3929 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 9:
420 goes into 1490 3 times with a remainder of 230.
The next digit of our result is 3. 
Result so far: 217469.3
Subtract 1260 from 1490 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 10:
If we divide 2300 by 420, we get 5 and a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 217469.35
The remainder is 200 after subtracting 2100 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
If we divide 2000 by 420, we get 4 and a remainder of 320.
Record the quotient 4 as the next digit in the result. 
Result so far: 217469.354
Subtracting 1680 from 2000 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 12:
420 goes into 3200 7 times with a remainder of 260.
Use 7 as the next digit of our solution. 
Result so far: 217469.3547
Subtract 2940 from 3200 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 13:
The number 420 fits into 2600 6 times, leaving a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 217469.35476
Subtracting 2520 from 2600 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.

On to step 14:
420 goes into 800 1 times with a remainder of 380.
Put 1 as the next digit of the answer. 
Result so far: 217469.354761
Subtract 420 from 800 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 15:
The number 420 fits into 3800 9 times, leaving a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 217469.3547619
Subtracting 3780 from 3800 leaves us with 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:
If we divide 200 by 420, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 217469.3547619
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 217469.3547619 and a remainder of 2e-07.
