99437420 ÷ 818 
We're looking to find how many times 818 goes into 99437420.

Advancing to step 1:
9 divided by 818 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 818

Moving on to step 2:
When dividing 99 by 818, we get 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Include the next digit (4) from the dividend after 99, then repeat: 994 / 818

Moving on to step 3:
If we divide 994 by 818, we get 1 and a remainder of 176.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 176 after subtracting 818 from 994.
Grab the next digit (3) from the dividend, add it to 176, then carry on: 1763 / 818

Moving on to step 4:
818 goes into 1763 2 times with a remainder of 127.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 1636 away from 1763, we end up with 127.
Append the next digit (7) from the dividend to 127 and continue with: 1277 / 818

On to step 5:
1277 divided by 818 is 1 with a remainder of 459.
Put 1 as the next digit of the answer. 
Result so far: 121.0
If we take 818 away from 1277, we end up with 459.
Grab the next digit (4) from the dividend, add it to 459, then carry on: 4594 / 818

Advancing to step 6:
818 goes into 4594 5 times with a remainder of 504.
Put 5 as the next digit of the answer. 
Result so far: 1215.0
Subtracting 4090 from 4594 leaves us with 504.
Take the next digit (2) from the dividend and append it to 504, then repeat: 5042 / 818

On to step 7:
When dividing 5042 by 818, we get 6 with a remainder of 134.
Record the quotient 6 as the next digit in the result. 
Result so far: 12156.0
Subtracting 4908 from 5042 leaves us with 134.
Grab the next digit (0) from the dividend, add it to 134, then carry on: 1340 / 818

Step 8:
If we divide 1340 by 818, we get 1 and a remainder of 522.
The next digit of our result is 1. 
Result so far: 121561.0
Deduct 818 from 1340 and we're left with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Moving on to step 9:
818 goes into 5220 6 times with a remainder of 312.
Write down 6 as next digit of the result. 
Result so far: 121561.6
Subtracting 4908 from 5220 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 10:
If we divide 3120 by 818, we get 3 and a remainder of 666.
Use 3 as the next digit of our solution. 
Result so far: 121561.63
If we take 2454 away from 3120, we end up with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Advancing to step 11:
818 goes into 6660 8 times with a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 121561.638
The remainder is 116 after subtracting 6544 from 6660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 12:
818 goes into 1160 1 times with a remainder of 342.
Put 1 as the next digit of the answer. 
Result so far: 121561.6381
Subtract 818 from 1160 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Let's proceed to step 13:
If we divide 3420 by 818, we get 4 and a remainder of 148.
Record the quotient 4 as the next digit in the result. 
Result so far: 121561.63814
Subtracting 3272 from 3420 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 14:
The number 818 fits into 1480 1 times, leaving a remainder of 662.
Record the quotient 1 as the next digit in the result. 
Result so far: 121561.638141
Subtracting 818 from 1480 leaves us with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Going ahead to step 15:
818 can be fit into 6620 8 times, resulting in a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 121561.6381418
Subtract 6544 from 6620 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 16:
818 can be fit into 760 0 times, resulting in a remainder of 760.
Put 0 as the next digit of the answer. 
Result so far: 121561.6381418
If we subtract 0 from 760, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Our division results in 121561.6381418 with a remaining 7.6e-07.
